| 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). |
| 11 | ANT | output | High frequency signal output, 50 ohm characteristic impedance |
| 12 | GND | Ground | |
| 13 | GND | Ground | |
| 14 | GND | Ground | |
| 18 | PB0 | Input /Output | NC PIN, This pin needs to be dangling and the user does not need to connect(for later extension use) |
| 19 | PB1 | Input /Output | NC PIN, This pin needs to be dangling and the user does not need to connect(for later extension use) |
| 20 | PB3 | Input /Output | NC PIN, This pin needs to be dangling and the user does not need to connect(for later extension use) |
| 21 | +3.3V | Input | Power pins for program loading (suspended, no need for user to connect) |
| 22 | SWIM | Input | SWIM pin for program load (dangling, user does not need to connect) |
| 23 | GND | Input | Ground pins for program loading (dangling, no user connection required) |
| 24 | RESET | Input | Reset pins for program loading (dangling, no need for user to connect) |
