| No. | Item | Direction | Description | Remark |
|---|---|---|---|---|
| 1 | GND | - | Ground | Ground |
| 2 | VCC | - | 3.3V | Power supply must be 2.0 - 3.6V |
| 3 | P2.2 | - | Reserved | - |
| 4 | P2.1 | - | Reserved | - |
| 5 | P2.0 | Input | Mode setting(MOD) | Falling edge: configuration mode; rising edge: transparent mode |
| 6 | P1.7 | - | Reserved | - |
| 7 | P1.6 | - | Reserved | - |
| 8 | SCL | Input /Output | I2C | I2C clock |
| 9 | SDA | Input /Output | I2C | I2C data |
| 10 | P1.5 | Output | Link status(LINK) | It is used to indicate the status of the connection. After the connection is successful, the pin outputs a low level. After the connection is disconnected, the pin outputs a high level |
| 11 | P1.4 | Output | Data indication(DATA) | It is used for serial port transparent transmission data output. The pin is pulled low before data transmission. After the delay is 10ms, the first byte start bit is output. When the last byte output ends, the pin returns to “high level” |
| 12 | P1.3 | - | Reserved | - |
| 13 | P1.2 | Input | Wake up(WKP) | Wake up: falling edge; sleep: rising edge. (Because of the jitter eliminating function, please keep the level within 20MS after the edge is generated) |
| 14 | P1.1 | - | Reserved | - |
| 15 | P1.0 | - | Reserved | - |
| 16 | P0.7 | Output | IO3 output | The output state of this pin can be controlled by the AT command (see the introduction of the AT command for details) |
| 17 | P0.6 | Output | IO2 output | The output state of this pin can be controlled by the AT command (see the introduction of the AT command for details) |
| 18 | P0.5 | Input | Disconnecting (DISC) | Falling edge will disconnect the current connection |
| 19 | P0.4 | - | Reserved | - |
| 20 | P0.3 | Output | Serial port transmission(TX) | Module transmits serial port data |
| 21 | P0.2 | Input | Serial port reception(RX) | Module receives serial port data |
| 22 | P0.1 | Input | IO1 inout | The output state of this pin can be controlled by the AT command (see the introduction of the AT command for details) |
| 23 | P0.0 | Input | IO0 input | The output state of this pin can be controlled by the AT command (see the introduction of the AT command for details) |
| 24 | RESET_N | Input | Reset(RST) | When the input level is low, it enters the hardware reset state. When the input level is high, it returns to the normal working state. This function is used for reset operation in emergency situations. |
