Power supply ：3.3~ 5.5V DC |
| 3 | AUX | Output |
To indicate module ’ s working status & wakes up the external MCU. During the procedure of self-check initialization, the pin outputs low level. Can be configured as push-pull output (can be suspended). |
| 4 | TXD | Output |
TTL UART outputs, connects to external RXD (MCU, PC) input pin. Can be configured as open-drain or push-pull output |
| 5 | RXD | Input |
TTL UART inputs, connects to external (MCU, PC) TXD output pin. Can be configured as open-drain or pull-up input. Ground |
| 6 | M1 |
Input （weak pull-up） |
Work with M0 to decide 4 working modes of module (not suspended, if not used, could be grounded). |
| 7 | M0 |
Input （weak pull-up） |
Work with M1 to decide 4 working modes of module (not suspended, if not used, could be grounded). |
