'''Main microcontroller:''' is a Spansion MB9BF002, a ARM Cortex M3 core, Ball Grid Array (BGA) package. The reset and SWD signals might be exposed to test points, I am not sure. | '''Main microcontroller:''' is a Spansion MB9BF002, a ARM Cortex M3 core, Ball Grid Array (BGA) package.

'''Bluetooth module:''' shows "8LA18366" and "GS-WCM-01" and "VR2.0". There is also a [http://en.wikipedia.org/wiki/QR_code QR code] that I can't decipher yet. There are a lot of test points near it. Underneath the EMI shields, it is confirmed to be a [http://www.qca.qualcomm.com/wp-content/uploads/2013/11/AR3002.pdf Qualcomm Atheros AR3002-BL3D]. | '''Bluetooth module:''' shows "8LA18366" and "GS-WCM-01" and "VR2.0".

'''Six-axis sensor:''' There's a rectangular | '''Six-axis sensor:''' There's a rectangular (maybe LGA) chip on the bottom side on the left, marked with "134" "A1322" "333": [http://www.bosch-sensortec.com/en/homepage/products_3/6_axis_sensors_2/inertial_measurement_unit_1/bmi055_1/bmi055 Bosch-sensortec GMBH BMI055] inertial sensor used for the three-axis gyroscope and three-axis accelerometer. 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. | ||
'''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. | '''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. | ||

'''Audio codecs:''' There's a {{G|QFN}} 32 pin chip marked with "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 {{G|SPI BUS}} with constant activity. There's also two resistors that look like {{G|I²C}} pull-up resistors, and there appears to be constant I2C traffic. | '''Audio codecs:''' There's a {{G|QFN}} 32 pin chip marked with "WM1801G" (Wolfson Microelectronics) "36A0LM6" dead center on the bottom side of the PCB.
