I did some research on the internal hardware of the i'm Watch Android watch and found out a few things:
The CPU is probably a MCIMX233CJM4B or maybe a MCIMX233DJM4B (the latter is only spec'd for temperatures down to -10 C, which wouldn't be suitable for a watch) and come in BGA169 packages.
Since the CPU only has 32 KB SRAM, external RAM is needed (supported types are mDDR and DDR1) and can most likely be seen next to the 4 GB flash and the CPU itself in the presentation video on their site (3:42).
The CPU has many things built-in such as a resistive touch screen controller, 1.5W speaker amplifier. It also has a host of interfaces; SAIF (Serial Audio Interface) which according to the data sheet could provide hardware accelerated Bluetooth audio, I2C, 2x SSPs, 2x UARTs, JTAG and USB with host mode.
The circuits are split into 2 separate boards, maybe with the Bluetooth chip on the board opposite to the one with the CPU on it.
The SSPs are basically highly configurable serial interfaces and also natively support the SDIO interface, which in turn might enable us to hack in some cheap SDIO WiFi card (found out there's a TI 1271 chip which someone used with Android and a Beagle Board link). Reaching this connector might not be possible from either the hardware nor the software side, but I'm an optimist .
Data sheet for the CPU is available here, I'd recommend page 33 and 1411 to get your inspiration going.
TL;DR
CPU is narrowed down to 2 options
WiFi might be possible with extensive hacking

huh, how to do what?
I picked one up
is there a major forum discussion somewhere for this watch?
I have one (since 3 days) and i think it is too soon for this kind of products.
The software is slow, battery should be longer than at least 5 days and bluetooth it is a technology than i never like it at all. By the way, if you try to use the i'm watch as a speaker, the quality is very poor for your calls.
on the other hand, this tecnology it is beginning and i believe future will be based on this kind of products.
C u!

it has a LOT of potential, im sure some smart folks can tweak it
Hi,
since people are saying no android phone is build like an iphone (with no any knowledge in electronic), I like to find the quality of the electronic inside.
Everything, if its possible , such as capacitor, transistor, resistor, chips, board, connectors, etc.
I'm pretty sure that I found a list for the iphone VS some android phone, but I CANT find it anymore.
Some one can help me with this? tks
Hi,
I want to make a small project and I thought of using N7 2013 LCD because this display have full-hd resolution 16:10. I know how to hook up a previous N7 lcd (2012 aka gen1) to DVI-LVDS adapter, but I wanted higher resolution
FYI: Designing and building pcb circuit is not difficult thing to do for me so this is not issue.
I tried to get in my hands a datasheet for LCD panel but no luck. The number printed on LCD is almost different for each display photo that I found - so this is not a panel symbol.
So the point is: I would like to ask someone that have ME571K repair guide, if he/she could share with me a part (screenshot) where is a LCD connector on motherboard described (signal names, pinout, connector manufacturer & part number).
I would be really happy, I sb actually shared a more information: a whole way from CPU to the LCD panel - this would be terrific - but this a little too much to ask

Hi, I don't have the pinouts nor repair guide, but here are manufacturer & part numbers...
Just search online for lcd monitor driver board ...you will find some good results
@k23m - thanks, but actually I need a other side connector of the LCD FPC P/N the one you connect to main board:
@deadgiveaway - you mean DVI/HDMI to LVDS adapter board? I know them (and I plan to use one but this is not issue), but I'm looking at least for a pinout of LCD FPC connector or the mainboard connector to lcd FPC (on the attached photo). Without this information the "adapter board" (DVI/HDMI to LVDS) is useless. I've done some reverse engineering on the FPC connecting mainboard with LCD and I've got in result some questions, e.g.: I'm certain there is a 6 differential signal pairs, but LVDS commonly use: 4 or 8, but I found in some datasheet there might be 6 too (rare case). Also the CPU Snapdragon have multiple video interfaces: HDMI, LVDS and (the worst case for me) MIPI-DSI.
Just got an some idea, there might be some information about display interface in /sys (linux/android file system path ) on Nexus 7.
Hi,
Thanks for attempts to help me. Unfortunatly I found out looking at /sys/calss/graphics/fb0/msm_fb_type ...
Code:
[email protected]:/sys/class/graphics/fb0 $ ls
bits_per_pixel

MIPI-DSI interface is no good for any use for me (there is no doc publicly available...). So I'm going to use lcd from N7 2012
Ps. For interested, is possible to use LCD from nexus 7 2012. A user aBUGSworstnightmare @ Raspberrypi forum, managed to hook up LCD from N7 2012 to DVI-LVDS converter/adapter: https://www.raspberrypi.org/forums/viewtopic.php?p=1052828#p1052828

Im trying to find the pinout moto x play or any other mobile displays. But I wasn't get any success
Can you tell me how did you get these pinout information
I'm doing a project on HDMI input to the display I found a module on hackaday project
Look fo service manual schematic for you phone. But almost always in displays that have resolution over 640*480 you find only mipi dsi interface. To get datasheet from manufacturer ( and MIPI DSI interface spec too ) is almost impossible [emoji3525] - unless you work for company and sign NDA with them for docs ...

Interesting, those are MTCD/E units, I ll get this thread moved to the MTCD forum.
They claim the resolution is 1240x1080 in those listings.
i don't тhink so, always 1024*600 is mentionned on theese product :/

Its mentioned in the spec sheet but in the pictures it says 1240x1080, the only way to be sure is to buy one I guess - they previously claimed that 1024x600 was HD but its isnt.
None of those items are available.
I have asked for the resolution of these PX6 model
Like: https://ljd.en.alibaba.com/product/...T.html?spm=a2700.7803241/c.0.0.4c8e3e5fwpqDt3
And 1920x1640 is not the resolution of the display. The display is still the stupid 1024x600 resolution. The device have the same stupid 10 years old video output RCA connector, USB 2.0, ....
I will wait some hardware upgrade not only CPU... in next 10 years !!! stupid !

I think youll be waiting for some time.
1024x600 is perfectly good even if it is a weird resolution.
Some RK3188/PX3 Lollipop units have HDMI out if thats important to you.

You are right;
- I know I will wait for a long time, and it is a shame because these Android radio are great …
- resolution, USB2, RCA can be enought, but it is 10 years old , and we want better like our phone, tablet, TV ….etc..
(RK3188/PX3 doesn't work correctly: perf, same display, USB2.... and I don't know why they didn't keep HDMI with PX6 because the CPU have HDMI output...)
I only want to say that these products could be very very very exceptionnal if not only the CPU was upgraded…
I do remember a few HDMI-out units, but most manufacturers seemed to have switched back to RCA video out. Honestly, the reason is probably becuase there is not much in-car gear with HDMI. I mean my headrest monitors are RCA-based, my backup camera is RCA-based and dashcams are usually USB or RCA-based.
What would you really use the HDMI out for?
I *do* wish that the audio-related internals and screens were better quality though (not really higher resolution, just higher-quality display types - no more TN displays). I also with they had anti-glare coatings. A super-reflective screen in the car is just a bad idea... And the CANBUS interfaces that generate sounds are just ridiculously bad. The turn-signal and warning chimes that my CANBUS module generates are laughable...
- "A super-reflective screen in the car is just a bad idea... " => Yes , it is so so true !¨"
- I understand than RCA is usefull too, but they can provide RCA and HDMI (like old PX3), it is not complex (hdmi pin is present on PX6) .
(I need HDMI for my HUD and at this time, I must connect it by USB + displaylink vdeo outut card which it use CPU. The resolution is not very good because the display resolution of the unit is low. (when I use MHL of my tablet, the result for my HUD is "perfect").
- and I need USB high speed for my phone, harddrive….
Unfortunately terrible glare is common even on new cars. Look at tesla that everyone is copying. Very rare to see cars with anti glare screens. Surprisingly more common on cheaper new cars.
I like there is innovated MTC revision after so long, but I will cowardly wait until there are some in stock in EU and first reviews by others come in
I've had 3 or 4 different aftermarket WinCE-based touch-screen 2DIN units in my GM and they all had anti-glare screens. It seems that when manufacturers switched from resistive-based touchscreens to capacitive-based touchscreens, they also lost the anti-glare coating. Eonon actually includes an anti-glare screen protector when you buy from them (at least some of them), which is nice, but unfortunately, they leave a small gap around the edge of the screen since they are a little smaller than the screen itself. For the life of me, I can't underatand why anyone would want such a reflective screen in the car... The nicest screen in the world doesn't do a damn bit of good if you can't see it. The anti-glare layer also significantly reduces fingerprints.
I have same grime with today's TVs even, no way around it. I'm accepting need for protector.
I'm new to all these head units, but from the looks of it, it is all the same with different face plate only - ie. touch buttons/volume rotary knob.
I will wait for px6 64gb in eu and finally give a try even if noone post review here or on 4pda
I mostly want it only for reversing camera though, but still Chinese android HU seems most reasonable, sad
I think those sellers are exaggerating about the maximum core speed.
There are 2 models on the marked, the A72 2.0 GHZ is the RK3399 PRO and the regular RK3399 A72 that run on 1.8 GHZ
http://www.rock-chips.com/a/en/products/RK33_Series/2018/0130/874.html
http://www.rock-chips.com/a/en/products/RK33_Series/2016/0419/758.html
Also these chips get seriously hot, so these chips realy needs a heatsink or a fan, not a simple coverplate like now on the px5.

Why would you assume that theyre "exaggerating about the maximum core speed" ? The RK3399 is available with 2Ghz so we ll assume that these RK3399 units use the RK3399Pro. If someone buys one and the max speed turns out to be 1.8Ghz then we ll know its a plain old RK3399.

How many sellers claimed that they selling a RK3188 @ 1.6 GHZ while they selling the much slower px3 RK3188-T that runs 1.4 GHZ. even the gpu is slower than the original RK3188. So it would be not the first time that sellers exaggerating.

Not that many.
We best wait for someone to get hold of a unit before judging . . .
We all know they'll put a new coreboard on the same motherboards and sell it as the next big thing.
Nothing else will change because the motherboards don't change and that's where all the other functions are.
The only change is this one will get hotter even faster since they won't dare put a fan or proper heatsink on them.

As I said, best to wait and see rather than speculate. Oh and the motherboards do sometimes change and some manufacturers do fit fans.
Would PX5 firmware run on these PX6 Units? Does it need to be recooked?
I have one live PX6 head unit.
