Product Introduction
This product is a Type-C to TTL serial port module that uses a CH340N USB bus adapter chip. It comes with three indicator lights on the board, one for power and two for communication. Because serial ports no longer exist on our computers nowadays, we usually use USB to serial port modules for the sole purpose of mapping the computer's USB port to a serial port.
Product Use
| 引脚 Pin |
引脚功能 Pin Function |
| VCC | 5V正极 5V positive pole |
| GND | 电源负极 Negative pole of power supply |
| RXD | 接收数据(通信时电压 5V) Receive data (communication voltage 5V) |
| TXD | 发送数据(通信时电压 5V) Sending data (communication voltage 5V) |
| RST | 复位引脚 Reset pin |
Special note
1. Before use, please confirm whether the Type-C cable has data transmission function.
2. The module directly outputs 5V voltage, but it can also be connected to the 3.3V pin of other devices for communication. For example, other CH340G serial port modules can be connected for data transmission and exchange.
