Pin number Pin name Pin Orientation Pin Usage
1 GND Input Module ground
2 VCC Input DC Module power positive reference, voltage range: 3.3 ~ 5.5V DC
3 AUX Output Used to indicate the working state of the module; the user wakes up the external MCU, and outputs a low level during the power-on self-test initialization; (can be left floating)
4 TXD Output TTL serial output, connected to external RXD input pin;
5 RXD Input TTL serial port input, connected to the external TXD output pin;
6 M1 Input (very weak pull-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 M0 Input (very weak pull-up) Cooperate with M1 to determine the 4 working modes of the module (can not be suspended, if not used, it can be grounded)
11 ANT Output Antenna interface (high frequency signal output, 50 ohm characteristic impedance)
12 GND - Fixedly
13 GND - Fixedly
14 GND - Fixedly
18~20 NC Input/Output NC pin, this pin needs to be left floating (for subsequent expansion)
