No. Name Direction Function
1 GND Input Module ground
2 VCC Input Voltage range: 3.0~5.5V DC
3 AUX Output Used to indicate the working status of the module; wakes up the external MCU, and outputs low level during power-on self-check initialization; (can be left floating)
4 TXD Output TTL UART outputs, connects to external RXD input pin.
5 RXD Input TTL UART inputs, connects to external TXD output pin.
6 M1 Input(weak pull-up) Work with M0 to decide 4 working modes of module (not float, if not used, could be grounded).
7 M0 Input(weak pull-up) Work with M1 to decide 4 working modes of module (not float, if not used, could be grounded).
11 ANT Output Antenna interface (high frequency signal output, 50 ohm impedance)
12 GND - Fixed ground
13 GND - Fixed ground
14 GND - Fixed ground
18 NC Input/Output NC pin, this pin needs to be left floating (for subsequent expansion)
19 NC Input/Output NC pin, this pin needs to be left floating (for subsequent expansion)
20 NC Input/Output NC pin, this pin needs to be left floating (for subsequent expansion)
21 NC Input (Users do not need to connect, to be left floating)
22 NC Input (Users do not need to connect, to be left floating)
23 GND Input Fixed ground
24 NC Input (Users do not need to connect, to be left floating)
