|---|---|---|---|
| 1 | M0 | Input（weak pull-up） | With M1, the four working modes of the module can be determined (it cannot be suspended, and it can be grounded if it is not used). |
| 2 | M1 | Input（weak pull-up） | With M0, the four working modes of the module can be determined (it cannot be suspended, and it can be grounded if it is not used). |
| 3 | RXD | Input | TTL UART input ,Connect to external TXD output pins; Can be configured as drain open circuit or pull up input, see parameter Settings |
| 4 | TXD | Output | TTL UART output, Connect to external RXD input pin; Can be configured as drain open circuit or push - pull output, see parameter Settings |
| 5 | AUX | Output | Used to indicate the working status of the module; The user wakes up the external MCU and outputs low level during self-test initialization; Can be configured as drain open output, or push-pull output, see parameter Settings(can be suspended) |
| 6 | VCC | Input | Positive reference of module power supply, voltage range: 3.3v ~ 5.5V DC |
| 7 | GND | Input | Ground |
