1. About IO port

The expansion board leads to all on board IO of ArduinoUNO, P2~P13 are digital pins, and A0~A5 are analog pins. A4 and A5 are used as IIC pins and are not additionally identified. Each pair of pins is paired with a set of VCC and GND and designed as a set of 4PIN PH2.0 anti-reverse interface (except for some pins).
