No. Name Direction Function 1 M0 Input(weak pull-up) Work with M1 to decide 4 working modes of module (not suspended, if not used, could be grounded)
2 M1 Input(weak pull-up) Work with M0 to decide 4 working modes of module (not suspended, if not used, could be grounded).
3 RXD Input TTL UART inputs, connects to external TXD output pin.
4 TXD Output TTL UART outputs, connects to external RXD input pin.
5 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)
6 VCC Input Voltage range: 3.0～5.5V DC
7 GND Input Ground
