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<br />
<br />
<br />
==About==<br />
<br />
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.<br> 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, <br>which have the characteristics of overcurrent protection, high performance, low power consumption, and low cost.<br />
