This USB to RS485 converter module( USB 1.1，USB 2.0，USB 3.0 compatible) can expand one RS485 asynchronous communication interface from a computer’s USB interface to realize the communication between PC and other RS485 devices.
The module uses a PL2303 chip and an easy-to-install driver. There are LED indicators on the module to show its working status: red for power, yellow for data sending, green for data receiving, which is convenient for system debugging. The baud rate of the module is 300bps-115.2kbps, and the RS485 transmission distance can be as far as 2km at the speed of 57.6kbps; The module can drive up to 32 RS485 devices, and the RS485 line is equipped with lightning protection, which effectively ensures the load capacity and working stability of the module.
Supporting Linux, Windows, Android, and Mac OS, this module can be applied to aviation and military system, high-speed railway electrical, railway dispatching, power station, and other industrial scenes, and other RS485 equipment driving.

Jargon buster
Plain-language definitions for the technical terms used above.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- RS485
- RS485 is a robust wired serial communication standard often used in factories, farms, and buildings where cables may be long or electrically noisy. It matters because it lets this controller connect to industrial sensors, meters, and control equipment over longer distances than typical hobby serial wiring.
