|---|---|---|---|
| 1 | GND | Reference place | Module ground |
| 2 | NC | - | Empty feet not connected |
| 3 | MO | enter | The combination of M2, M1, and M0 determines the 8 working modes of the module (cannot be suspended, if not used, it can be grounded) |
| 4 | M1 | enter | The combination of M2, M1, and M0 determines the 8 working modes of the module (cannot be suspended, if not used, it can be grounded) |
| 5 | M2 | enter | The combination of M2, M1, and M0 determines the 8 working modes of the module (cannot be suspended, if not used, it can be grounded) |
| 6 | 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 |
| 7 | TXD | Output | TTL serial port output, connected to the external RXD input pin; can be configured as open-drain or push-pull output, see parameter settings for details |
| 8 | AUX | Output | Used to indicate the working status of the module, the user wakes up the external MCU, and outputs low level during the power-on self-check initialization period. It can be configured as an open-drain output or push-pull output. For details, see parameter settings (can be left floating) |
