| Serial number | Pin Definition | Pin Direction | illustrate |
| 1 | GND | -- | Power Ground |
| 2 | PD6 | -- | Reserved GPIO, users do not need to worry about |
| 3 | PD7 | input | Internal pull-up, falling edge, and then keep low level for at least 5 seconds, all parameters are restored to factory settings and the module is automatically restarted. |
| 4 | PA3 | -- | SWS; program download pin; users do not need to care; |
| 5 | PA7 | Output | Connection status indication pin, high level indicates connected, low level indicates disconnected |
| 6 | PB2 | input | Battery voltage detection pin |
| 7 | RST | input | Reset pin, low level reset |
| 8 | WKP | input | Low level low power mode; High level inputs working mode |
| 9 | RXD | input | Serial port input |
| 10 | TXD | Output | Serial port output |
| 11 | GND | -- | |
| 12 | VBAT | -- | Positive power supply, 2.0V~4.2V, 3.3V power supply is recommended |
| 13 | PB7 | Output | The default is low level, and the effective level is high; There are two modes: long-acting and inching; can be set through the serial port or WeChat applet; the pulse width of the inching mode supports the configuration of 10~65535ms |
| 14 | PC0 | Output | The default is low level, and the effective level is high; There are two modes: long-acting and inching; can be set through the serial port or WeChat applet; the pulse width of the inching mode supports the configuration of 10~65535ms |
| 15 | PC1 | Output | Complementary PWM output; can be configured through the serial port or WeChat applet; long-term or electric mode, frequency, duty cycle, (dead time), PWM duration (10~65535ms in inching mode); |
| 16 | PD2 | Output | |
| 17 | PD1 | -- | Reserved GPIO, users do not need to worry about |
| 18 | GND | -- | Power Ground |
