USB to RS485 Module

The USB to RS485 Module allows a computer to interface directly with industrial RS485 networks using a standard USB port. It is ideal for makers, engineering students, and technicians working with automation, telemetry, and multi-device serial communication.

Reliable serial communication bridging

This converter module extends an asynchronous half-duplex RS485 interface from a computer USB port. It is fully compatible with USB 1.1, USB 2.0, and USB 3.0 standards.

CH340 controller and multi-drop support

Equipped with a CH340 interface chip, the module supports parallel connections to drive multiple RS485 devices simultaneously. It accommodates transmission baud rates ranging from 2400bps to 115.2Kbps.

Integrated lightning protection and rugged range

Built-in lightning protection on the RS485 data line maintains signal integrity and stable operation under load. The module operates with a low 1W power consumption and withstands working temperatures from -40°C to 85°C.

Cross-platform operating system compatibility

Driver support spans Windows, Linux, Android, and Mac OS systems. It is suitable for applications across railway dispatching, power stations, industrial control systems, and field equipment monitoring.

Compact enclosure and package contents

Measuring approximately 83mm by 26mm by 17mm, the compact module easily fits into portable toolkits and control cabinets. The package includes one USB to RS485 converter module.
