Serial number pins Pin direction Note
1 GND Input Modular ground wire
2 GND Input Modular ground wire
3 VCC Input Module power supply positive reference, voltage range: 4.5~15VDC
4 VCC Input Module power supply positive reference, voltage range: 4.5~15VDC
5 RESET Input Module reset pin
6 THE output It is used to indicate the working status of the module; The user wakes up the external MCU, and the output is low during power-on self-test initialization
Level; (can be suspended).
7 TXD output TTL serial output, connected to external RXD input pins;  
8 RXD Input TTL serial port input, connected to external TXD output pins;  
9 M1 Input (extremely weak pull-up). In conjunction with M0, the module determines 4 working modes (not suspended, if not used, grounded).
10 M0 Input (extremely weak pull-up). In conjunction with M1, the module determines 4 working modes (not suspended, if not used, grounded).
11 GND Input Modular ground wire
12 GND Input Modular ground wire
13 ANT output Antenna interface (high-frequency signal output, 50 ohm characteristic impedance).
14 GND Input Modular ground wire
15 GND Input Modular ground wire
16 GND Input Modular ground wire
17 GND Input Modular ground wire
18 GND Input Modular ground wire
19 GND Input Modular ground wire
20 STATE output The module status indicates the output, as long as no dover processing is used
21 485-EN Input/output The enabling control pin of the external 485 chip can be used if the suspension is not used
22 NC - No need to care, suspended processing
23 NC - No need to care, suspended processing
24 NC - No need to care, suspended processing
25 SWDIO - No need to care, suspended processing
26 SWCLK - No need to care, suspended processing
27 GND Input Modular ground wire
28 3.3V - No need to care, suspended processing
29 NC - The bottom of the module is reserved for matrix pads, and users need to use the heat dissipation of the module after grounding, please refer to the PCB packaging diagram in the relevant download place of the official website of Yibaite for detailed dimensions


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