Main functions of the product
Native CP2102 chip USB to TTL module, drive-free support for four major operating systems. 3.3V/5V level automatic switching, stable communication up to 1Mbps. Micro USB interface versatility, built-in 500mA power output for the target device power supply. With hardware flow control (RTS/CTS) and ± 15KV ESD protection, it is suitable for scenarios such as microcontroller burning, industrial equipment debugging, and IoT gateways.

Product main pin function
VCC: Power output positive provides 5V/3.3V power to the target board (maximum 500mA)
GND: Power ground termination target board GND
TXD: Serial Send Terminate Target Device RXD (Output Data to Target Board)
RXD: the serial port receiving end is connected to the target device TXD (receiving target board data)
DTR: Device ready signal for MCU automatic reset (e. g. Arduino burn)
RTS: Request to Send Signal Hardware Flow Control/Reset Control (configurable)
