USB to RS232 COM Port Cable 0.8m CH340

USB to RS232 adapter (COM port) is a proven solution for connecting older devices such as printers, fiscal cash registers, or satellite tuners that use the RS232 serial port. The device creates a virtual COM port, ensuring smooth communication via USB 3.0, USB 2.0, and USB 1.1 connectors. The product is also an excellent tool for communication with popular platforms-Arduino, ESP8266, ESP32, and Raspberry Pi.

Installation is as simple as plugging the cable into the computer’s USB port and then into the RS232 socket on the target device. The adapter is based on the popular and reliable CH340 chip, enabling stable data transmission at speeds up to 1 Mbps. The converter is compatible with many operating systems-from Windows 98SE through Windows 10 (64-bit). Drivers can be downloaded from: https://sparks.gogo.co.nz/ch340.html
