>
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.~
