Main parameters	performance		Remark
Main parameters	minimum value	maximum value	Remark
Supply voltage (V)	0	5.2	Exceeding 5.2V will permanently burn the module
Blocking power (dBm)	-	10	Less likely to be burned if used at close range
Working temperature ( ℃ )	-40	85	Industrial grade

Pin number	Pin name	Pin direction	Pin usage
1	RESET	enter	Module reset pin, 3.3V.
2	GND	-	Module ground wire
3	NC	-	Empty feet (not open for use, users do not need to care)
4	NC	-	Empty feet (not open for use, users do not need to care)
5	NC	-	Empty feet (not open for use, users do not need to care)
6	NC	-	Empty feet (not open for use, users do not need to care)
7	NC	-	Empty feet (not open for use, users do not need to care)
8	GND	-	Module ground wire
11	GND	-	Module ground wire
12	ON	output	Antenna interface (high frequency signal output, 50 ohm characteristic impedance)
13	GND	-	Module ground wire
14	GND	-	Module ground wire
15	GND	-	Module ground wire
16	GND	-	Module ground wire
19	GND	-	Module ground wire
20	M0	Input (very weak pull-up)	Cooperate with M1 to determine the two working modes of the module (cannot be left floating, can be grounded if not used)
21	Lock	output	Module synchronization indication. A high level indicates that the two parties are synchronized and data transmission is possible; a low level indicates that the two parties are not synchronized. Transmitting data at this time will result in data loss.
22	RXD	enter	TTL serial port input, connected to the external TXD output pin;
23	TXD	output	TTL serial port output, connected to the external RXD output pin;
24	TO	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-test initialization; (can be left floating)
25	VCC	-	Module power supply positive reference, voltage range: 2.3~5.5V DC
26	GND	-	Module ground wire
