1
Pin No. Pin Item Pin Direction Pin Application
1 GND Input Module ground
2 VCC Input Power supply :3.3~ 5.5V DC
3 AUX Output Used to indicate the working status of the module; the user wakes up the external MCU, and the Output is low during the power-on self-test initialization Level; (can be left floating)
4 TXD Output TTL serial port output,connect to external RXD Input pin;
5 RXD Input TTL serial port input, connect to external TXD output pin
6 M1 Input(weak pull-up) work with M0, to define 4 working mode(not floated,connect to ground when not using )
7 M0 Input(weak pull-up) work with M1, to define 4 working mode(not floated,connect to ground when not using )
11 ANT Output Antenna, 50ohm impedance
12 GND - fixed orifice
13 GND - fixed orifice
14 GND - fixed orifice
