Review:

It feels really good to hold.

Teardown photo album: http://imgur.com/a/ytRW5

The USB port and LED are on one separate board, connected using a flat flexible cable, this cable is connected to a vertical FFC connector that does not have a locking mechanism.

The touchpad sensor is also detachable, connected using a flat flexible cable, this cable is connected to the main PCB using a connector that has a flip-up locking mechanism.

The speaker is not removable and it connects to the main PCB using some raised contacts.

The battery is 3.65V 1000mAH Li-ion.

Main microcontroller is a Spansion MB9BF002, a ARM Cortex M3 core, BGA package. The reset and SWD signals might be exposed to test points, I am not sure.

The Bluetooth module shows "8LA18366" and "GS-WCM-01" (or maybe it's "GS-WCN-01") and "VR2.0". There is also a QR code that I can't decipher yet. There are a lot of test points near it.

There's a chip marked with "BD9200" (in QFN 32 pin footprint) that might be a PMIC because it has some thick traces around it, plus a big inductor. One of the pins near it read 6V, might be for the motor.

There's a shiny small square chip left of the left analog stick, it is marked with "7710" "325A1", I have no idea what this is, but there's some differential signals coming out of it, it might be USB, the activity stops when I disconnect the USB cable.

There's a rectangular (maybe LGA) chip on the bottom side on the left, marked with "134" "A1322" "333", possibly a sensor

There's a QFN 32 pin chip marked with "WN18016" "36A0LM6" dead center on the bottom side of the PCB. It has a sine wave logo on it. It is near the audio stuff but it is also near where all the buttons connect. There are 5 test points near it. It appears to be communicating with SPI with constant activity.

Some buttons are active low, some are active high (maybe only the thumbstick push buttons). The sheet of flexible circuit for the buttons are active low.

I'll keep adding to this section
