Note: The module must be connected to a 50 ohm impedance antenna when sending, and sending without load may cause permanent damage to the module! ! !

Pin number	Pin name	Pin Orientation	Remark
1	GND	Input	Module ground wire
2	GND	Input	Module ground wire
3	VCC	Input	Positive reference of module power supply, voltage range: 4.5~15V DC
4	VCC	Input	Positive reference of module power supply, voltage range: 4.5~15V DC
5	RESET	Input	Module reset pin
6	AUX	Output	Used to indicate the working status of the module; the user wakes up the external MCU, and outputs a low level during the initialization of the power-on self-test; (can be suspended)
7	TXD	Output	TTL serial port output, connected to external RXD input pin
8	RXD	Input	TTL serial port input, connected to the external TXD output pin
9	M1	Input (very weak pull-up)	Cooperate with M0 to determine the 4 working modes of the module (not floating, if not used, it can be grounded)
10	M0	Input (very weak pull-up)	Cooperate with M1 to determine the 4 working modes of the module (not floating, if not used, it can be grounded)
11	GND	Input	Module ground wire
12	GND	Input	Module ground wire
13	ANT	Output	Antenna interface (high-frequency signal output, 50 ohm characteristic impedance)
14	GND	Input	Module ground wire
15	GND	Input	Module ground wire
16	GND	Input	Module ground wire
17	GND	Input	Module ground wire
18	GND	Input	Module ground wire
19	GND	Input	Module ground wire
20	STATE	Output	Module status indication output, if it is not used, it can be handled in the air
21	485-EN	Input/Output	The enable control pin of the external 485 chip can be suspended if it is not used
22	NC	-	Don't worry, just leave it in the air
23	NC	-	Don't worry, just leave it in the air
24	NC	-	Don't worry, just leave it in the air
25	NC	-	Don't worry, just leave it in the air
26	SWDIO	-	Don't worry, just leave it in the air
27	GND	Input	Module ground wire
