| Pin No. | Pin name | Pin orientation | Pin usage |
|---|---|---|---|
| 1 | GND | - | Module ground wire |
| 2 | GND | - | Module ground wire |
| 3 | GND | - | Module ground wire |
| 4 | GND | - | Module ground wire |
| 5 | M0 | Input (very weak pull-up) | Cooperate with M1 to determine the 4 working modes of the module (can not be suspended, if not used, it can be grounded) |
| 6 | M1 | Input (very weak pull-up) | Cooperate with M0 to determine the 4 working modes of the module (can not be suspended, if not used, it can be grounded) |
| 7 | RXD | enter | TTL serial port input, connected to the external TXD output pin;Can be configured as open-drain or pull-up input, see parameter settings for details. |
| 8 | TXD | output | TTL serial output, connected to external RXD input pin;Can be configured as open-drain or push-pull output, see parameter settings for details. |
| 9 | AUX | output | It is used to indicate the working status of the module; the user wakes up the external MCU, and outputs a low level during the power-on self-test initialization; it can be configured as open-drain output or push-pull output, see parameter settings for details. (can be left floating) |
