3 GND - Ground
4 GND - Ground
5 M0 Input (weak pull-up) Work with M1 to decide 4 working modes of module (not suspended, if not used, could be grounded).
6 M1 Input (weak pull-up) Work with M0 to decide 4 working modes of module (not suspended, if not used, could be grounded).
7 RXD Input TTL UART inputs, connects to external (MCU, PC) TXD output pin.
8 TXD Output TTL UART outputs, connects to external RXD (MCU, PC) input pin.
9 AUX Output Used to indicate the working status of the module; The user wakes up the external MCU and outputs low level during power-on self-check initialization; (can be left floating)
