APC220 Pinouts
- VIN: Module power supply
- GND: Ground
- RX: Data receive through serial protocol
- TX: Data transmit through serial protocol
- SET: Mode Setting
- AUX: For other commands
- EN: Enable module
Use Arduino's pins GND, 8, 9, 10, 11, 12 and 13.
It only need four pins connect with Arduino board.
Note: Disconnect the RX and TX pin with Arduino before download program, otherwise the program download fails.
