Product Name
LC USB to four-way TTL serial port module USB to four-way UART with built-in LED indicator light onboard 0.5A fuse overcurrent protection PH2.0 horizontal patch terminal
About
The LC USB to Four TTL Serial Port Module is developed based on the CH344Q chip, which can convert one USB interface into four UART serial ports.
It has a Type-C 5V DC input, built-in LED indicator light, and a 500mA fuse on the input board. It supports overcurrent protection and uses PH2.0 horizontal patch terminals,
which have the characteristics of overcurrent protection, high performance, low power consumption, and low cost.

Module usage instructions
1. Install USB drivers on the computer
Official driver download website
2. Connect the input end to the computer USB port, and connect the TX and RX of the output end with jumper caps.
At this time, the LED power indicator light will light up
3. At this point, open the USB device viewer or the built-in device manager on the computer,
which will display information about the USB device and four COM ports
4. Open the serial debugger, select one of the serial port numbers, choose the appropriate baud rate, open the serial port and send data.
The window will receive this data without packet loss, as shown in the following figure:
