No. Name Direction Function
1 GND - Module ground
2 GND - Module ground
3 GND - Module ground
4 GND - Module ground
5 M0 Input (very weakpull-up) Cooperate with M1 to determine the 4 working modes of the module. (Can not be suspended, if not used, it can be grounded)
6 M1 Input (very weakpull-up) Cooperate with M0 to determine the 4 working modes of the module. (Can not be suspended, if not used, it can be grounded)
7 RXD Input TTL serial port input, connected to the external TXD output pin;
8 TXD Output TTL serial port output, connected to the external RXD 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)
10 VCC - Module power supply positive reference, voltage range: 3~3.6V DC
11 GND - Module ground
12 NC Reserved (OCDSCK)
13 GND - Module ground (GND)
