Asus T100 hardware tear down - Hardware Hacking General

Since I can't post anywhere else for some reason, here goes my hardware tear down for the Asus T100 (T100TA for experts ):
Visible chips on the T100TA mainboard Rev 2.0:
Amtel MXT1664TXES-C2U 1330B TW QLG9F (Touchscreen controls)
Broadcom BCM43241SFKFFBG TN1322 P24 294688 P3T (WiFi)
Phison PS2251-68-5 UO1329C D75J0.11AA (USB3.0 controller)
Realtek ALC5642 D2L87HI GD13F (Audio)
Winbond 250(Q)64FW1G 1329 6236 QP30003 (BIOS/UEFI)
Intel Q326A657 SR1M5 02962 '12 (the main cpu Z3740)
M F20 P02 CFQ0589 (No idea)
ITE IT8568VG 1331-AXO ZC0P1A (No idea)
SANDISK 9.15 XC4*00 SanDisk32G (The eMMC storage unit, 32GB version)
Camera module:
HannStar J 94V-0 E89382 1335 MV-4
Unnused connector J601 can be found on the camera module. Seems to be an USB connector.
Pictures of the hardware/inside: [NOT ALLOWED]
Got the hi-res versions stored locally, can't find a good place that doesn't rape the resolution / jpeg compression rate. Now, I was thinking the Winbond chip is most likely the PLL, isn't it? Should open the doors for some FSB tweaking. Another thing I couldn't find was the recovery USB storage... 7GB according to the hardware manager of Windows 8.1 . Unfortunately it uses 'current read-only state: true' which makes it impossible to use it as extra storage (try it with diskpart for yourselves).
Also, for other Dutch users, this is my main Dutch thread on Tweakers: [NOT ALLOWED].
If people can help out with identifying the chips / giving additional information it would be greatly appreciated

thanks for the teardown...

unused connector would be nice. I have a small microSDXC USB reader, looking through your pics to see if there's any space to fit it there
would like to see the battery model number. C12N1320 ?

C12N1320 Yes, or CL12NL320, but I am pretty sure they would use "L" instead of "l" then. As you probably have seen, it has two batteries connected to each other. How exactly I don't know, didn't want to remove the black cover sticker. :silly:

Is the RAM socketed or is it non-removable as my only issue is the 2Gb (1.89Gb usable) RAM available.

I used some tools that were leftovers of my HTC Leo / HD2 days. Pretty much a guitar pick, but it might be a little thinner. I recommend starting on top, it goes the easiest loose there. The screen side is hooked to the backside, so best to pull the backplate a little outwards when removing, it will snap the hooks loose. For the dock, I will upload hires pictures soon of its contents, I did pull it apart before but my phone doesn't make great photos: imgur dot com slash a slash NQdTb http://imgur.com/a/NQdTb

SANDISK parts
Hi, I would like to know the appropriate part no. of Sandisk 32G. Could you pls see and let me know it ?
I may help you to identify of the specification in detail.
Thanks, Ricky:laugh:

I'd like to know this too if anyone knows. Is it soldered into the board or is it a microSD?

Its a Sandisk SEM64G or 32G if you have the 32gb. Just reflashed mine from the stock bios to 220 and now everything is working great and no more bsod while using adobe flash or gaming in d3d. Thanks for those pictures they have saved me the hassle of looking to see if a ram upgrade to 4gb is possible and its not. No matter around october 2014 there should be something better to trade up to with hopefully 4gb and 128gb ssd minimum.

Thank you very much for your information.I think that recovery USB storage is located here (marked on the attached picture). Can you please make the pictures of this area and connector J601 with higher resolution
Phison PS2251-68-5 is a controller usb 2.0 is used in flash drives. i think it is a controller for recovery USB storage

It seems there is a non USA model of this T100TA that has a 500GB hard drive inside the dock. Would a mod be possible for the USA version?

I think so. They could have soldered it to the board though... I haven't seen a teardown of a 500GB model, would love to see what is inside too! Maybe it can even help us Europeans to mod ours to have the same capabilities :good:.

Anyone know where the WiFi antenna is?
I'm really impressed with how well this tablet hold on to my WiFi signal across the road. I have a Yagi and a panel antenna beaming through tree branches, a balcony and a brick wall. Despite all this it doesn't seem to struggle to hold on any worse than my laptop did which had two antenna. You would think this low power chip would perform much much worse.
Even speed wise considering this doesn't have MIMO so the link speed is down from 150Mbit to 64Mbit, real-world speed is not as much of a reduction as I thought it might be when I realised it didn't do MIMO.
I have even seen this thing get 20Mbit across the road where my laptop used to peak around 30Mbit, although on average I get nearer 5Mbit now whereas the laptop did 10-20Mbit more frequently.
I did try an external mini USB adapter on the T100, didn't work any better even though THAT was linked at 150Mbit and the built-in only does 64MBit.
As for the HDD model, I read on another forum that its definitely in the keyboard and a different board to the normal one. Its interesting though, makes you wonder if it uses a hub or are there actually spare connectors on the dock?
What I personally would like is a dock adapter you can use while still in tablet mode that just adds the USB 3.0 port. If we are REALLY lucky maybe someone will trace the dock connector?

Any hint of a connector for the HD in the dock?
Thanks for the teardown info. As far as I've found these are the only ones on the web so far.
Its hard for me to see from the pictures. Did you see any hint of what/where the HD would connect in the dock?
Thanks,
Eric

The HDD dock keyboard has a different PCB to the normal keyboard. Below is the normal one taken from http://www.transformerforums.com/forum/asus-transformer-book-t100/39507-inside-t100-base.html:
What I'm curious about is if the whole dock runs off a single USB 3.0 port or does the dock connector have several ports?
It would seem unlikely that its run off a hub as many USB 3.0 devices have issues if not run directly from a native port and I notice my USB 3.0 HDD works fine.

I took a look on mine and windows doesn’t show any USB 3 hub between my USB 3 thumb drive and the Root Hub, so I’d say there isn’t a hub there. I also did a little digging to make sure there wasn’t an embedded hub in there which might show up differently. I looked at the xHCI extended capability values and the host controller is advertising 6 USB 2 ports and 1 USB 3 port. That makes me even more curious what protocol will be used to connect to the HD in the dock. Hope it’s not USB 2.0.
If you go into windows device manager, go to the view menu and change it to "view by connection" you can then browse the device tree in a hierarchical way that will show you what is connected to what.
In Windows 8/8.1, if you find your external HD in device manager BEFORE you switch to “View by Connection” then when you switch the tree will automatically expand to show it. Under the xHCI controller there will always be a Root Hub listed. If you HD shows connected directly to that then there is no hub.
What chips are on the pcb in the dock?

I will ask the guy on the Transformer forum who took the photos as I don't want to take mine apart.

Is the wifi card a mini pcie? Or a different interface I may want to upgrade mine.

3/4g internal modem.

I'm looking to start a thread about turning an a500 into a a501. I've done a teardown of the a500 and it has the capability of potentially being able to support an internal card. It has the space/slot and screw mounts.
Before I start ordering and soldering parts to the circuit board I'd like to get a few facts straight.
1. The firmware (kernel) between the a501 and a500 are the same? I've heard that it is, and that it isn't
2. Drivers- obviously drivers will need to written. No way of getting around that.
3. PCIe Riser extender - As you can see from these pictures, the plastic bracket is missing/not included. You can see on each side there is two holes for mounting the bracket. I'd recommend the extended below, as it will allow me the needed length between the two.
http://www.amazon.com/PCI-Express-Riser-Flexible-Cable/dp/B0054CIL46
The reason I'm picking this is because I can solder this
Here is the empty space:

Now here is the space with a pcie wlan card
You can see from the last picture that there is a space issue that needs to be addressed.
I would need to use riser with an extended back end inorder to align up this the screw mounts.
this picture is just of the screw mounts.
I've seen a few threads now about the idea of this , nothing really taking liftoff, so I thought I'd be the first to start.
Also, is there a command for listing hardware/chips in android , using android terminal emulator. Something like lspci (linux command)
**********************************************************
On to pcie 4g/3g cards.
Here is the 4g card I found:
http://www.ebay.com/itm/Intel-5150-...135?pt=LH_DefaultDomain_0&hash=item43a38d57f7
I'd rather have one with the major cellular provides, but I can't seem to find any. Clear has a basic 200mb (holy hell) for $20. Not bad for 4g coverage.
3g Card
http://www.ebay.com/itm/Inspiron-15...118?pt=LH_DefaultDomain_0&hash=item5645ae677e
This one is cheap, and from verizon.
$30 /2gb plan from verizon.

Still learning basic programming.I've taken a programming fundamentals and half of programming structures. Teacher was Indian and had us read from a book. If someone wouldbwrite the driver I would jump into it
wow .. really interesting ..
now u know what would be even better ?
to have this module external.
to be able to connect it to the a500.
anyway ..
sure hope u get something..

I agree!! Your average XDA user is open minded when it comes to flashing roms, kernels and different types of software mods but they aren't that open minded to cracking their device open and screwing around with things internally. A usb type of module would be great!! I KNOW you're properly thinking like "WOW, do you want it to clean your house too" BUT T'll put my wallet where my mouth is and will donate 75 dollars if you can get this thing working via usb or provide some sort of brick-proof way of doing this.
I'm really excited to the idea of possibly having 4G on this tablet!!
Good Luck!!

It looks like its missing one of these..
Mouser is a great source for parts like this. It will involve soldering a connector and possibly writing a driver.
Once you find out the parts requirement, any electronics repair shop can handle it.
http://www.mouser.com/Interconnects/Memory-Card-Connectors/_/N-72bz7/
I can't help anymore then this, I don't own one of these devices. However, kernel=drivers. You've got two issues. Kernel support and Hardware. Once you've got the physical connection done, search for some linux devices which uses similar hardware and grab the kernel modules built for your kernel. If you're lucky, you can just insmod them into the device. If you're not lucky, you'll need to build from source.
Would a kernel dump or source from an A501 do the trick? I don't have one, just throwing around ideas...
A little background: I'm an electronic engineer with some experience of teardown work.
I agree with Adam that you need a socket rather than trying to solder a flexy on.
Do you have any teardown information on the A501, or would someone with an A501 be willing to get photographs. I think the key hardware things to find out are 1) what socket is used for the card and 2) what card is used.
If you get a 3g card with the same chipset on, then wouldn't it be as simple as hacking in A501 firmware for the driver?

That one itself would be the ideal. But that makes sense.
The story doesn't end at installing the card mount, but also needs other components to work. Instead you can tear down a 2 port USB hub, tear down your 3G modem and Stick it in an empty place do some soldering so that the end result should be as follows........
1. The socket which generates USB inside the case, should be fed to the USB hub,
2. One output of the hub should go to the USB dongle we earlier ripped out
3. The other output of the hub should be the cable that extends to the outside USB port.. after all we need this USB also for external USB for attaching keyboards, flash drives etc..
I hope I gave a unique idea here
You need to see a real 3g version to know if other thing missing like transistor on board neer pci card, or usb its more sure
Look for version 3g before investigate pciMe 3g and pciMe connector also sim connector of course

Yes this one what i do it cause you can found mini usb 3g and open it to integrated on board
This was attempted once before and was proven that the boards of the A500 and A501 have differences! Somewhere here in the forum was a thread and there were diagrams and photos of the tho devices! There are many missing components on the A500 that will have to be mounted and it will surely be cheaper (better working) to sell the A500 and get an A501 if you so much desire 3G!

It is nice idea, but you should know that the hub as well as the dongle need power. If the USB output on the device itself is not giving enough power for both of them then it will not work or not work reliably.
Of course the battery will also be drained much faster as all the power saving measures do not affect the hub and the dongle.
And as for the pci connector: maybe you could compare the A500 with the A501 model and see if there are other parts missing. Usually not only the connector is left out but also some other parts on the board itself. So it may be much more soldering and work as you originally though of.
well that's depressing to know. that brscket in the fifth post was what I'm looking for.
can someone post a link to that thread with the pictures if the two teardowns?

Goood you understood what I meant with. Definitely the USB out port of the Tablet can handle both. you should buy a two port low power hub and try on
I also did the analysis of power usage, and found that the power used by the hub is really miniscule, and can be used with ease. You must appreciate that the Max power is drawn by the screen rather than the other hardware components, and inevitably the power consumption will increase once you add a 3G module in the tablet, as in A501. So the total power consumption is well within the limits.
I did the practical experiment of leaving the data ON on the tablet, overnight, and I find no extra power usage than without, in the sleep mode.
The only challenge in both the cases is that you have to change the Rom. Either the stock 501 Rom or one of the marvellous custom Roms. I am personally using Virtuous Galaxy 1.0.5 , with an overclock and code for 3G modem, that works seamless.
Once I do this activity I would post a video , or at least a set of pictures.
Sorry i dont know much about these devices but I am not sure what usb has to do with it??? looks like a mini pci e slot to me... (correct me if i am wrong) it cant harm to try soldering the points together.. swap the kernel from the 501 over as long as its got the same build and you have r/w to the system partition and see what happens...

Did you read all posts? I don't think so.
it does not harm to solder a socket there but it will not work as there are for sure other components for that pcie slot missing.
As for the USB solution read the earlier posts as this is a solution, which would work.
Another type of wimax card for clear is the one inside their Rover puck wifi point. no one talks about it or i have seen a picture online but i got one that just works fine, its a half size pci-e mini card so you would have more space to move it around and the antennas come with it, just find one with broken usb port and open it to get the card.
As for driver info i will post with pic of card, it uses the same driver as their clear 4g stick,(grey and black color)
I know it's a bit 'off topic', but.. Since the Iconia has this 'slot', do you think it would be possible with the xoom too??
Check this out: http://guide-images.ifixit.net/igi/5oVhXNLhi3U1AZRy.huge
Step 8 from iFixit --> At first glance, this appears to be a Wi-Fi board, but wait: there are no chips on it! It appears to be just a mini-PCI interconnect board for the antennas. This board is probably just a place holder for when the 4G upgrade becomes available.
Back on topic:
The Iconia A501 has the Qualcomm MDM6600 chip on one of it's boards or it's just a modem? I ask that because by seeing the Xoom 3G teardown we find the said chip. It seems that the chip is missing on the Xoom WiFi according to some here: http://www.ifixit.com/Answers/View/45910/Wifi+Only+Xoom+upgradable+to+4G+LTE
So, if you are missing some key parts of the system, I don't think it would be possible to just add a modem to the list of bills to make it 3G/4G unless it's just a software lock?

Thinking of performing a hardware mod for USB hosted microsd/bluetooth(Kindle Fire)

Ok, so i'm ordering a replacement digitizer and I figure this would be a good time to try this out.
As you all know, we Kindle Fire owners have neither expandable storage or bluetooth. Hashcode's new 3.0 kernel has the proper kernel modules/support for USB hosting. Instead of having to plug things in every time I need/want extra storage I figure that i'll try and hook up the stuff inside.
So here's what I figure i'll do when I get all the materials:
I already have a mini bluetooth USB dongle that i've disassembled.

Now, the easy part is finding space to put them, there are a few gaps/spaces that I found for the bluetooth dongle, and placing the microsd adapter should be just as easy.
The hard part is getting the wiring all wired up on the inside, and this is where I need advice/input. Trying to solder the wires to the pins on the charge/USB port would be too hard and risky since they're so close.
I took apart a mini-b USB cable to use the pins to try and hook them up like that some way, but I don't have everything I need yet, so it's just a thought.
Ideas, advice, thoughts and/or comments?
Also, I will be documenting what i'm doing so that I can post a tutorial if I succeed.
I've also posted this in the Kindle Fire general forums. http://forum.xda-developers.com/showthread.php?p=25212300
Main problem with the SD adapter is that many USB SD readers behave badly if you insert the SD when the adapter is live - you need to insert the SD THEN plug the reader into a PC.

Hmmm, thanks for bringing that up, I didn't think of that. I'll have to see about putting a small switch in somewhere if I run into that issue.
Have you looked for another USB pinout on the board?
There might be one, if you can post an hi-res picture of the PCB I can try to find something useful

I was going to try and do that myself, but I couldn't find anything. Right now I ended up scraping off some of the black plastic around the pins at the point that they're going up and i'm trying to solder them alternating the top and bottom.
If you can find other places though that would be great. It might help me out, and it would def help others out if I succeed and write a tutorial.

There's something I don't understand here; won't doing this render the USB port unusable? Don't you need a hub if connecting more than one USB device? Can the USB port provide enough power for these additional devices?

You need the USB hub for power from what I understand. The microsd adapter doesn't require any power and i'm not sure how much the bluetooth takes, but since the other takes none it might work out. If they don't work together then it doesn't really matter to me cause I don't need bluetooth.
Also, about it making the USB port unusable, yes and no. If you look at this pinout diagram here http://www.kineteka.com/microusb-b.aspx you'll see that there are 5 pins. On a USB cable only 4 are used. On a USB otg cable pins 4 and 5 ar econnected telling the device that it's a host and not a slave. When pins 4 and 5 are connected are connected USB will not work at all(So no adb or file transfers, etc.) because the cable is being told it's a host device. Once those two wires are separated then USB will work again because it will see itself as a slave device.
I searched info trought the TI OMAP 4430 documentation about the USB implementation.
(i have to "hide" the link or i won't be able to post!)
Here you can find a block diagram of a reference USB implementation:
h_t_t_p://w!w!w.ti.com/pdfs /wtbu/OMAP4430_ES2.x_DM_Public_Book_V_D .pdf
Section
A.4.4.2 USBA0 PHY Implementation Example
Also, Section
2.1 Terminal Assignments
Shows the pinout of the processor
Table
Table 2-1. Ball Characteristics
Shows the chip connections
The document lists also USB0, USB1 and USB2 but i can only see ball pinouts for "usba0_*" and anything like "usba1_*" or "usba2_*".
So i think that there's only one USB connection and you'll have to solder a USB HUB somewhere between the CPU and the USB connector.

Thanks for the help, but how am I going to solder directly to the processor?
And if I could get the correct pins anyways there would be no need to use USB I could just hook the microsd up directly since the 4430 already has those.
If there was a data sheet somewhere out there for this specific board something like what you're suggesting might be possible, but it's not really the way it is now.
And i've never used USB host capabilities before, but from the videos i've watched people on other devices don't use a hub unless they hook up more than one device.
I see. You are right!
Anyway, i came up with another solution for the bluetooth connectivity: it requires a bit of soldering and a couple of kernel modules (or a custom-built kernel).
You can solder some wires from the serial port of the kindle fire:

to a UART bluetooth module:

Then write a script the brings up the bluetooth interface at boot.
In Linux should be feasible, in Android i don't know... maybe there's a praticular framework that needs specific drivers...

**Disregard**This could help with bluetooth if I can't get USB host to work, but that still leaves no solution for the sdcard, which is my primary concern. I've actually gotten all the wires soldered onto the correct pins on the usb port, but I can't get USB host to work for any device, with or without the correct modules.**Disregard**
You got me thinking though, I could probably add a UART sdcard and GPS module on like that. Awesomeness, thanks for the idea. I'll try that out if I can't get USB host to work.

I've also seen a lot of hardware mods that connected sdcards to gpio lines. That could be an option too.
For the sdcard over UART it's possible, but i'm concerned about the performances...
At 115200bps baud rate you get 14.0625KBps!!!

True, true. You seem to have more experience then I do at this. I'll prob buy a GPS UART module and do that. I have the wires soldered onto the USB pins on my Kindle, but I haven't had time to do anything more then that yet.
Thank you
A GPS module will be very useful.
A 7" tab it's portable enough to be carried around and used with a simple car mount...

I don't really understand why using the usb-port should be a Problem. Just solder your what-ever-you-want-device to the original usb pinout, it's big enough. Solder a rly small switch (taken from an old mobile Phone for example) between pin 4 and 5 to change host and normal mode. Finally, if u need more power there of course is a battery inside the Kindle, get it from there
I'll receive my Kindle in a few days i hope (u can't buy it regularly in germany...), will play a bit with this stuff

I've already got the wires soldered to the pins, I just wasn't able to get USB host working. And there's no room for a switch right on the pins, but I thought of a good solution. Reed switches!

The UART modules are only an idea, the main problem with going that direction instead of USB host is the drivers the modules would need(They all usually come with generic ones, but they would need to be customized for Android). I have very limited code/coding knowledge so I would need alot of help or soeone to do that part completely. I was going to pm Hashcode for help if I decided to try out the UART modules. Also, i'm unsure if more than one module can be used at the same time.
Like I just posted in the thread i'm still waiting on some stuff to arrive to actually get started on the USB host attempt. I have the wires soldered to the USB/Charge port pins, but since I don't have the microsd adapter or any more spare cords to rip apart I can't go further. I ordered about 10 different mini microsd adapters to take apart and see which works out the best.
Other people have USB host working, so shouldn't be difficult. I've just never used USB host before so i'm not real sure of what to expect.
The only downside is that there needs to be a switch of some sort somewhere to disable USB host so that adb/storage will work. I'm trying to think of something a little more elegant that having a huge hole in the case with a switch protruding out of the side. I'm going to go searching for some solutions and a super small switch.
All the UART GPS modules I found when searching "uart gps module" on Google are mostly from India and are between $30-50ish, the receivers look to be about the size of a quarter.

All the optimism aside i'm not all too sure that we could get the GPS UART module to work. From what I see (First picture: http://forum.xda-developers.com/showthread.php?t=1471813) the UART output that Hashcode put into use only has two GNDs a TX and RX. The modules that I found all look like they need 8 connections. Adafruit has a nice pic of the connections labeled here: http://www.adafruit.com/products/746
If you're talking about microsd UART modules, as mentioned in the thread I created, someone made the point that it wouldn't make much sense because speeds would be way too low.

Hiking GPS Tablet

So I'm thinking I'm going to tether via wifi my phone's GPS with the NST. Has anyone done this? Is there a good offline map pack for eink devices?
Let me know your thoughts...
EDIT:
So I did it last weekend and it works great. Downloaded some Topos from Rmaps after rooting and turning on mock locations via SQLite on the NST. Installed GPS Tether on phone and NST. Turned on phone hotspot, then tethered the NST to the phone and blamo! GPS. I already have a solar panel I wired up and will attach to the backpack to charge both the NST and the external battery for the phone.
Meet Earl was my inspiration.
I have not tried that, but I did just order an Earl for the same purpose. Maybe you could use whatever they use for maps.
I cant post links, but google meetearl.
One of the problems with USB is that it is a bit power intensive.
Also, running things off USB you need to convert 3.3 V to 5 V to 3.3 V
If I were trying to turn the Nook into a hiking map I would...
Get a GPS module that runs off 3.3V, maybe this: http://www.adafruit.com/products/790
Connect it directly into the internal 3.3 V serial port on the Nook.
I don't know what you'd have to do for the antenna.
You'd probably need an external antenna, but external to the case or not is the question.

Feeding GPS data from one device to another - there is no much need for such an app, shouldn't be a problem to write one using Mock Locations provider.
I was wondering, what uses more power: external USB GPS or WiFi tethering?
iGo Primo claims it works with 1.6 and up
Sygic: GPS Navigation & Maps - 2.0.1
TomTom: 2.2 and up

Hey Renate NST, do you have any more detail about how you'd go about this? I bought a Nook ST last week for exactly this purpose (though I also want to install a solar panel on the back of it and weatherproof the whole system), and actually have one of those GPS chips you listed (on a breakout board though) from an old project with an RPi.
So in terms of the next steps... (apologies for the dumb questions, this is the first time I've properly played with something not intended to be played with)
- How do I find the serial port? I've spent about ten minutes looking at the board and haven't found it.
- How do I then get a maps program (I'm using rmaps at present) to take the serial input as GPS input? Will I need to parse the NMEA?
Thanks in advance,
Jake
The UART for /dev/ttyS1 is detailed here: http://forum.xda-developers.com/showthread.php?t=1702734
I haven't looked too closely into serial NMEA-0183 working on the Android.
I have gotten the USB version to ouput via a cat.
It seems that most folks who do that just read and parse it themselves then use the Android "mock location" interface.
The "mock location" is so that you can playback a trip from Boston to San Francisco without driving anywhere.
It seems that it would be cleaner to not go through the "mock location" interface.
Now you've used this for a while how long does the WiFi last on your phone and how long on the Nook?
Even if not saving battery at least we can read the screen this way
GPS on USB
I'm using the following:
- NST glow
- OTG cable (micro USB male, regular USB female)
- reduction (regular USB male, mini USB male (and an extra USB for external power, but haven't tried that so far))
- GPS unit (QStarz BT-Q1000XT)
- USB mode utility app
- UsbGps4Droid app
Works perfectly. I haven't noticed any substantial power drain, but I switch the GPS off after a few minutes every time...
I use it mostly with Osmand, but it seems to work with any other app.

Its a really small GPS module (SparkFun) going directly into the Nook UART. Currently looking to drop the battery voltage to 3.3 for V_BAT of the GPS Here is the current state:
Black - GND
Orange - VCC 3.3 (goes off with screen saver)
Blue - RX
Green - TX
The switch is for putting GPS to sleep mode.
Yup, direct to the UART is the way to go.
I guess the ceramic antenna is too big to fit inside the Nook between the aluminum plate and the top case?
I think that I'd cut a rectangle out of the Nook top case at the top for clearance,
run the wires inside the Nook and glue a tiny box on top.
I haven't checked that connector to see if there were any UART control lines or GPIO on it.
That would be the nice way to control the power mode of the GPS.
Just a quick one to say watch out on Sygic. It's a great and slick program and downloading new maps is easy. But it's made plenty of my phones run hot; it's CPU intensive probably and a battery drainer. Q: What's a battery efficient mapping app?
RMaps: Very probably light. I don't think it's very slick.
There's an app for OS maps in the UK offline: You can then preload the >8gb of maps to get full UK, very nice maps. Probably the best option. I think you have to pay for the Android app though... don't know how that would work... don't know if it's supported on Nook
iGO, TomTom: Also sounding CPU intensive. It seems vector and nav capabilities are what make these things battery draining. Stick to raster maps? (images rather than route calculable vectors)
It's been a long while but no news on this for ages.
The earl is still not out. It's also expensive.
This hack is pretty cool. The USB option is the easiest... but we can't have a USB cable hanging out the bottom, ready to rip off the mainboard rendering the whole thing useless.
So I prefer the option of soldering directly onto that UART with the GPS module.
yegoshin, what did you use to get the voltage right?
There's lots of info in the comments here:

So you can use the direct battery voltage from the nook for the VCC, you can also use pin 1 off U2713 (however I have recently run into what seems a lack of current through that - GPS doesn't lock until I plug in a USB power really weird, no problems off the Battery though pink wire is the VCC)
Now for the V_BAT I was able to wire up this board to the nook battery https://www.sparkfun.com/products/10995 and pull 1.8Volts off that. However that board has ALOT of excess parts (its meant to be used with this GPS, which I think may work even better for the nook since the on-off can be done via that breakout board) I may look into getting a custom board stuffed.
If you happen to be near Bay Area CA, I can help you out.
Woah, I didn't know about this tiny 1.8V logic GP-2106: https://www.sparkfun.com/products/10890
You don't need any level conversion, ttyS0 (UART1) is all 1.8V logic.
(You'd need to make sure that you aren't using ttyS0 for the console.)
You can grab one of the JTAG signals (also 1.8V) for the on/off control.
See the pinout here: http://forum.xda-developers.com/showthread.php?p=49931617#post49931617
You could 3D print a tiny housing and mount it on top of the bezel right over the "nook" at the top.
Something to look out for is that 5 second, 50 mA anomaly that we haven't chased down yet.
The power consumption will kill you.
Latest news?
Hi guys,
Just come back off a hiking holiday, and have been looking into using the NST as a low power, eink gps for UK OS maps etc.
Your prototype here looks spot on!
How far did you get with this - any guides etc?
Also, if someone felt like making these, 3d printing a new, deeper back case for all the extra electronics - i'm sure you'd have a nice lot of customers !
(NB looked at your pics of soldering direct onto the serial connectors internally... Woah! Bit beyond my soldering skills there!)
Good luck, would love to hear updates...

USB Host support

It pains me to do this, as I was hoping B&N will step forward and release an OTG/USB Host cable. The hardware is certainly all there.
But alas, they are sitting on their hands again, so I have no other choice but use this software override kludge again.
All for the better most probably, as I suspect when they do release, it'll cost some outrageous amount of money, just like what happened to the HDMI adapter.
If you want to try it yourself.

After reading around, one can use a battery pack with pass-thru USB function to connect high-powered devices like a USB HDD. Continuing this line of thought, it should be feasible to connect said battery inline to an unpowered USB hub, and convert said hub to powered. Am practicing some Google-fu to find a decent pass-through USB battery now.

Try "battery powered usb hub"
I was hoping you have some actual models in mind. Your key terms resolve to the same blank wall. There are plenty of "battery hubs" shown, but AFAICT all of them are AC-powered hubs that can charge battery-powered devices. The need for a portable (battery) powered hub isn't new, and I've searched for it before. I was thinking of DIY, but a hub + inline passthru battery pack looks to be the least hassle at this point. Again, would appreciate any more integrated solution you know of.
Welp nothing that some window shopping can't cure, as me sis would say.

Well, the very first link on that google search is to this amazon item: http://www.amazon.com/CyberPower-Mobile-Battery-Powered-CP-H420MP/dp/B0002UQALQ/ref=pd_sxp_f_pt
which is eaxactly a usb hub with AA batteries. Granted, it's no longer available for sale, but there are more of those, I saw them when I last looked a couple of years ago so I know there must be more.
That seems a lot of power draw to be practical, unless a chunky hub to last very long.

Did you measure it? Does not seem too bad in my testing.
Just my looking at the draw having two things hooked up. If you are using one usb drive and no other devices, it should last several hours. Better than taking the load via the tablet battery. Sharing the drain love is good.
so the gender changer usb host thing only works with cm10.1 and not on stock?

This is correct.
For stock you need to have this special cable that B&N never made available (but certainly had plans for).
Shoehorning a new kernel into stock is too much of a hassle too.
But if you are an enterprising individual, you can trace the id pin on the pcb to see where does that connect in the connector and make your own otg cables, resell for huge amounts of money and profit

[Q] asus transformer t100

hey guys , i saw in a review of this new win 8 tablet, the guy said the bay trail cpu can run android with no problems, i am totally buying this tablet, but has anybody tryied to install android in it, or along win 8? thanks guys..
Someone would have to compile Android x86 for it. I'm not sure how well the current Android x86 isos out there would support the hardware. You could always run Android x86 through Virtualbox, the downside being performance would suffer since your tablet would be running Android on top of Windows.
I dont think they have shipped to consumers yet.
For now you have virtualbox (or VMware, I get better performance with VMWare but virtualbox is more straightforward) and android-x86. Or "Jar Of Beans" or bluestacks. I think a regular ARM build of android has been tried in QEMU too but on a bay trail this will be unusably slow, heck, its near enough unusable on a god damned core i7.
Bay trail doesnt have the operating system lock that clovertrail had. So yes, it should be able to boot android-x86 natively, but android-x86 doesnt support all touchscreens, bluetooth or wifi, chances are on the t100 it wont work properly. Android-IA is far better than android x86, but is device specific so you will have to hope that there is an Android IA build for the t100 *or* someone makes a compatible build of android x86 for the t100. It is theoretically possible though.

ubuntu is currently booting to grub, crashing on x-server and getting a working interactive shell

Have you tried a headless linux install yet? Might be a start.

Might try to take teh dock apart and see if I can fit a battery in it. I have a couple portable charges that go up to 12000mah
I might wonder if I could fit one in there maybe a 5000mah or a 8k. I might have to take mine apart to see how everything is laid out.
But on a side note I still need to get one. Anyone know where a 32GB one can be bought?

with flat batteries, and some sanding maybe? but you'll either sacrifice the usb port, or have to integrate a usb hub in there somehow, or just wire the batteries in the data pins only... I'm interested in that too, may look at hardware mods once the software mods get going enough
if you plan to do a (full) teardown of the dock / the tablet itself, lmk...

Wiring into the data pins will kill the USB controller. Guess you probably meant the +5v and GND pins.
Do you know if anyone has reverse engineered the dock connector pinout? Chances are you will not be able to wire a battery into the system from the keyboard on the USB port.

I was going to use the interface form one of the ultra thin portable chargers that has a 2amp output. I was going to use the USBin it and mount it on the opposite side of the current USB 3.0 and there may be room on the sides of the touchepad. I will try once i can get my hand on one.
I was then going to use a thin and short usb cable I made to wire it to the USB port on the tablet part that I can plug and unplug when needed. .
How about trying a dock from one of the Android transformer series? they all come with built-in batteries..
I was thinking it might work if the connectors and latches are the same!

Confirmed to not be compatible.
Asus will release a T100 with a modified keyboard T100TA-DK007H - 64GB eMMC with 500GB built internally. Makes you wonder what other things you could pop under the hood.
As for running other OS, seems booting is way to complicated at the moment. Anyone tried running Gennymotion VM on it yet?
Screen question
Hello!
hope im at the right forum ... i have been using my t100 for 2 days now and im in love with it XD
i had the slow charge problem with it but 2.20 bios fixed that ... now im using 1.2m cable that came with my logitech keyboard (the cable trully is of top quality) and original charger (need to try it out with my s4 charger) and it fills up in about 4 hours.
My question is about the screen ... when i close it when its in the keyboard ... there are only options to "shut down", "sleep" or "do nothing" ... is there a way to turn the screen off while the tablet is still turned on ... like on laptop if you choose "do nothing" it will stay on but the screen of the laptop will shutdown.
Cheers!

Sure man, just go to control panel, power management, change settings, and here set time to go to sleep after 4-5h. Then, change advanced power settings and make screen to turn off after 5 mins. This way, you can leave PC tuned on, while screen is off...
T100 Slow WiFi with External Monitor
When I connect my T100 to an external Monitor then wifi becomes extremely slow, 1 - 2 mb/sec and much of the time I get the unable to connect msg in the browser.
Windows shows that I am connected to my wireless lan.
It only happens if the cable is connected to the monitor. Connecting the cable to the T100 without a monitor does not affect the wifi speed.
It only happens if the t100 is set to display something on the external monitor. If I set it to internal only then even with the external monitor connected, then the WiFi is fine.
Monitor is Dell U2410. I am using a minihdmi to hdmi adpapter and a three foot hdmi cable.
I was completely updated with all windows updates. Not all ausus updates installed. I did install the latest bios update, 220 I believe.
I also tried rolling back to a system restore before I updated all the windows drivers but that did not help.
Can someone else test their network speeds with an external monitor?
Any ideas how to fix?
T100 Slow WiFi with External Monitor
I tried a different WiFi access point in my home but that did not help. Windows shows plenty of signal strength for the WiFi network connection, but I just get a bad data rate.
Without an external screen connected then the WiFi connection is good. It is much more reliable than for my Old Asus Transformer Infinity TF700 tablet.
If I connect a Unitek wired ethernet converter to my USB port and use that for networking then the data rate is ok, so the problem is definitely related to WiFi. I am wondering if anyone else sees the same behavior or if it is just my device.

That sounds really really weird, shouldnt happen though.
I've read there's a chunk of metal as counterweight located in the keyboard. Asus took that out and put a 500Gb HDD instead. Maybe you could put a battery instead?

It is in fact a counter weight and I have confirmed that removing it will cause it to fall over when opened. LOL
As far s running Android... why? Android makes a great mobile OS and works fine on tablets, but this particular device is a desktop PC, in tablet FORM.
Full Windows, not RT, MS Office included, etc... It is part of what makes it so appealing... While I am a huge Android fan, to put that on this device would seem like a downgrade to me.
I would love to see a keyboard base with extra storage and battery though...
