Thông số kỹ thuật:
Pin No. | Pin Name | Input/output | Functions |
---|---|---|---|
1 | NC | - | Reserved, directly suspended |
2 | GND | - | Ground |
3 | NC | - | Reserved, suspended |
4 | PD3(WAKE) | Input | The WAKE The wake pin is mainly used to wake up the sleepingterminal. The default value is high level. When the pin is pulled down, the sleeping terminal device will wake up |
5 | PD7(TX) | Output | Serial transmission port TX |
6 | PA0(RX) | Input | Serial receiving port RX |
7 | NC | - | Reserved, suspended |
8 | NC | - | Reserved, suspended |
9 | PD4(MODE) | Input | Working mode switch pin, when pull down time is more than 500ms, switch working mode |
10 | PA1(BAUD_R) | Input | UART_ BAUD_ The reset pin is used to reset the baud rate of the device. The default value is high level. In any mode, if the pin is pulled down for more than 1000ms, thedefault baud rate will restore to 115200 |
11 | PB1(ACK) | Output | The ACK pin is used to indicate the status of the last user data transmission. The pin is pulled down before the transmission is started, and it is pulled up after the transmission is down |
12 | PC0(GPIO0) | Input/output | GPIO input/output port 0 |
13 | VCC | - | Power supply |
14 | GND | - | Ground |
