| Serial Number | Pin Definitions | Pin direction | illustrate |
| 1 | GND | - | power ground |
| 2 | I003 | - | Reserved GPIO, users don't need to worry about it. |
| 3 | RESTORE | input | After the internal pull-up switch is held low for at least 5 seconds, all parameters are reset to factory settings and the module automatically restarts. |
| 4 | I012 | Output | The data output indicator outputs a high level upon receiving BLE data over the air and a low level after the BLE data has been transmitted via the serial port. |
| 5 | LINK | Output | Connection status indicator pin: high level indicates connected, low level indicates disconnected. |
| 6 | I011 | input | Reserved GPIO, users don't need to worry about it. |
| 7-11 | GND | - | power ground |
| 12 | NC | - | - |
| 13 | VBAT | input | Positive power supply, 1.8V~3.6V, 3.3V recommended. |
| 14 | 3V3 | Output | DC 3.3V |
| 15 | 3V3 | Output | DC 3.3V |
| 16 | WKP | input | The default low level is in low-power mode, and serial communication is disabled. Pulling it high inputs normal operating mode, and serial communication is enabled. (Edge triggered) |
| 17-19 | GND | - | power ground |
| 20 | RESET | - | Reset pin, low level reset |
| 21 | RXD | input | Serial port input |
| 22 | TXD | Output | Serial port output |
| 23 | SWEDING | - | Reserved GPIO, users don't need to worry about it. |
| 24 | SWCLK | - | Reserved GPIO, users don't need to worry about it. |
| 25 | I018 | Output | Log serial port output is disabled by default; it can be left floating if not used. |
| 26 | I020 | - | Reserved GPIO, users don't need to worry about it. |
| 27 | I004 | - | Reserved GPIO, users don't need to worry about it. |
| 28 | GND | - | power ground |
