The touchpad sensor (with Atmel 8-bit AVR Microcontroller ATiny2313) 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. | |||
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. Underneath, it is confirmed to be a Qualcomm Atheros AR3002. | |||
' | 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. I think this is connected to the USB port. I suspect this is a OTG chip. | ||
There's a rectangular (maybe LGA) chip on the bottom side on the left, marked with "134" "A1322" "333", possibly a sensor. It's got some sort of latch signal around it, or maybe it's a weird clock. It's slow and doesn't seem like a bus. Or it could be a shift register and it's reading blank because I'm not pressing buttons. | |||
There's a | There's a {{G|QFN}} 32 pin chip marked with "[[:File:WM1801G.jpg|WM1801G]]" (Wolfson Microelectronics) "36A0LM6" dead center on the bottom side of the PCB. 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. There's also two resistors that look like I2C pull-up resistors, and there appears to be constant I2C traffic. | ||
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. | Some buttons are active low, some are active high (maybe only the thumbstick push buttons).
