bc10
Keypad †
This is the information of the keypad board, which is connected to the left expansion slot (from AMOLED side) of bc10.
This board is attached to the oppose side of the standard expansion board (which comes with power supply). To use this
board, a keypad can be added at the other side of the standard expansion board. This board has a pad, which is used for
connecting GPIO (x4) and UART1.
