This thread is dedicated to the development of an inductive charging mod for the Galaxy Note 8.0.
To sum up what is already known:
The Note 8.0 DOES NOT have built in wireless charging capabilities.
Generic 500mA Micro USB Qi receivers do not appear to work (It isn't yet known if 1000mA ones do)
In another thread I had identified 2 large contact pads at the bottom of the mainboard which were particularly interesting. Mainly because they were right near the connector to the Usb board as well as the battery connector.

These contacts are not used for anything else such as a speaker or antenna (at least on the Wi-Fi version).
I strongly suspect these are some sort of power connectors, perhaps used for testing the mainboard without the USB board.
Neither of the two large pads are connected to Ground nor VCC, but some of the smaller pads are.
If there is anyone has a bricked Note 8 and would like to donate it's PCB, it would definitely help with figuring out what these contacts are. High res pics of the other side of the mainboard would work as well.
Update:
Well it's now been over a week and a half since the used mainboard I ordered off eBay was delivered to the wrong address. The seller, 268warehouseparts, has been of little help and my neighbors seem to have a need for a GT-N5110 motherboard and have refused to return the package.
I am probably going to end up eating the cost of the board. With that said I have no further plans pursuing this mod.
There also doesn't seem to be much interest in it anyway.

I am very interested in wireless loading my Note 8. I think its not the
greatest problem finding a point to connect, but I dont find a
solution getting the needed current which is at least env. 1 A.
All offers for wireless loading units are about 500mA which is definetly
to low. SO are there transmitter/receiver combinations with needed
current please let me know, then we will try to find a way to connect it in the note.

What port is that?
Why does this Nexus 7 not have that port?
I have a funny feeling its a HDMI port, but only for certain Nexus 7 devices. The Xperia Play Developer version had the same thing, but the normal one they sell doesn't have one. So it may be a "developers" Nexus 7 with a HDMI port.
Just my thoughts...
Yeah, looks like a micro-HDMI port.
Probably found on the developer and/or internal versions for mirroring to external display during presentations (like on yesterdays keynote).

I think you mean Mini, right?
Nexus 7 with no HDMI is a big deal-breaker for me.
I agree it looks like a Mini-HDMI port.
Well, from the schematics that were posted today, I have a feeling that is a JTAG port, since it's located right beside J1 (a 24pin connector on the main board) that has serial and JTAG IO pins. It would be good for the engineers not to have to keep opening the unit to flash it vis JTAG, which is a LOT faster than flashing over USB.
What schematics are you referring to?
Edit: Never mind, I found the thread.
The nexus 7s from the unveiling event had micro hdmis for presenting them on the big screens. That's where these pictures are from.

It's probably a HDMI connector. But HDMI is usually already supported (on other platforms) by running an MHL output over the micro-USB. This would explain why they didn't bother adding that port to production line. (It's always better to have to buy external adapters, right!?)
However, for the Samsung Galaxy S3, there have been some confusion, which seem similar to what you got there...
PS. JTAG is very unlikely. They'd never redesign the entire case just to add a JTAG port.
Wow, nice work digging up an old thread. (look at that date gap...). The presentation N7s had HDMI ports.
Go check out some of the other threads from this date (the day it was announced) and you'll see this question was asked, debated, fought over, and confirmed several times here on XDA.
A lot of discussion about aftermarket chargers and car chargers, but I cannot find specs for original nexus/asus charger that you get in the box.
Is it the same as this one?: http://www.asus.com/Peripherals_Acc...Nexus_7_10W_Adapter_and_Cable/#specifications
If not, could someone please post exact specs of the charger (everything written on it) for UK and EU (i know they are most probably exactly the same, but I want to be sure)
Also, since the UK charger comes made out of two parts (as seen in any nexus 7 UK unboxing video: https://www.youtube.com/watch?feature=player_detailpage&v=bfd8ithIxFg#t=229s ), is there a EU version of this? Because UK plug is the only one with detachable plug, as far as I've seen US and EU come normally, without any detachable parts. Is it a very specific part, or can I go to some local electro store and get EU plug?
Thanks!
Really, everyone talking about how they're enjoying their nexuses, and NO ONE will take 1 minute of their time to copy specs off the adapter?
Please, it's not too hard to do.
This is the very same universal charger that comes standard with the Nexus 7. If you care to read the label of yours, you'll see it's exactly the same one, specs (and looks) wise.
Regarding the detachable adapter, I think the one included in the "ASUS Traveller's Kit" for the Eee Pad TF101 is fully compatible but unless you can find someone who's willing to sell you this specific detachable plug in separate, you might as well buy the official ASUS Nexus 7 adapter specific to your country.

I will read charger specs myself in two weeks, when I indeed do get it. For now, I don't have it just yet, and I can't find info on it. I'd basically only like to know output current, so I can compare it to my Sony and Samsung chargers.
About the travel kit, thanks for the tip! Too bad the Eee pad has a completely different plug, and I'm not paying 30$ just to get the EU plug
Even the charger alone is quite expensive. I guess I'll just use one of those massive bulky traditional travel converters
Thanks for answering!
Hi. I'm in the idea stadium of a DIY car holder/charger since the ones out now looks stupid to me.
I need a smaller charger like the Nokia dt-900 which people tell me doesn't work well with n4 (comments on that?)
While looking at what is out now I've come to notice one thing (many actually), some sellers say that to get the n4 to work with their chargers you have to place the phone high on the charger in order to line up the coils. Looking at LG's charger this looks false:

The charger is placed above the phones centre line. This isn't really that a big issue but anyway strange.
The charger I need also need to be powered at 5 or 12v to simplify installation in car.
Please feel free to help me with your findings in this matter.
As for the DIY details, I'll let you in later on.
EDIT: The phone has to be high on the charger, not the opposite as I wrote :s
The Nokia chargers don't work well with anything pre- Hardware Revision 12 (if I remember correctly). So if you have a brand spanking new Nexus that says it is Revision 12 the Nokia might work.

It needs to be revision 13.

What's the difference between revisions that makes it work?
I thought the problem with the nokia charger was that it didn't provide enough power to actually charge the phone reliably.
Hi,
I'm after an external battery pack, preferably with quite high capacity, that has a micro-usb port to charge the pack. I've seen like mini-USB one's and the DC in but I need a micro-usb one to make things easy for me
Have you come across one like this?
Cheers
check my instagram post. 2nd from the latest. can't get the short URL since I'm on my phone right now. instagram: ijustzeke

I have this as my backup
http://www.amazon.com/Lightning-Sen...413913&sr=8-2&keywords=anker+external+battery
It's more than enough.

Don't know if you can charge it via microusb though, not released yet.
I've had good luck with Anker's internal batteries in the past (HTC Sensation) so I'd trust their battery packs. Not sure off the top of my head if any of them charge via microusb.
http://dx.com/p/cager-b030-10000mah...er-w-adapters-sd-slot-2-led-light-grey-167568
The cager ones look to have a microusb port, although I can't vouch for the quality of the batteries. Considering the N4 can support usb-otg with a custom kernel and external power, the cager may be a nice touch if you are looking for external storage via sd card.
the anker astro3 (10,000mAh/ 3A) charges with a micro-sd cable -- there's a short curly one supplied (+ alternative tips) which you can then reverse to charge the N4 from the Anker.

i got mine for £25.99 shipped from amazon uk and i'm very satisfied with it. it's about 20% larger and heavier than the N4.
So I used to have a Galaxy Note 3 and the NFC chip was on the battery. I thought the same was the case with my V20 until I bought one of those extended 6600mAh batteries (because I dont really care about the thinness of the phone) which doesnt support NFC. I noticed the lack of the black ribbon around the camera and the 2 contacts on it. Im assuming this is the NFC chip? Do you guys think it would be possible to peel it off and stick it on the new back cover that comes with this extended battery? NFC is something I use daily for NFC payments (since its widely available in Australia) and would love to still be able to use it.
Pic for what I mean

Splitting hairs, but what you see around the camera cutout on the cover is the antenna for the NFC chip. Chip is on board itself.
Honestly, I would imagine it would work, were you to be really careful about pulling the ribbon off..
That said, practicality of the matter is another thing entirely. those damned ribbon cables are crazy fragile. like, dont look at it too long, or you'll tear it fragile. and, i imagine it is stuck to the original cover with some sort of adhesive or another.
tl;dr
the odds of a botched removal are too damned high!
I'd actually like to know about this myself. Considering the v20, with the extended batteries as a main point as I hate being grounded to a charger, but NFC seems like something i would like to start to use as mobile payments are being accepted at more and more places. If you try it, let us know how it goes. Maybe you can put tape on the sticker to give it more support? Who knows. If you mess up, I'm finding spare back covers with NFC antennae for around 20 USD on Amazon.
