USB TO RS485 Converter (CH340)

The USB to RS485 Converter (CH340) is a compact and reliable serial communication adapter that enables communication between USB-enabled devices (such as PCs or Raspberry Pi boards) and RS485-compatible devices. Powered by the CH340 chipset, it ensures stable performance and compatibility across multiple platforms. This module is widely used in industrial control systems, Modbus communication, embedded projects, and long-distance data acquisition applications due to RS485’s noise immunity and multi-device support.

Key Features:
• CH340 USB-to-serial chip ensures wide OS compatibility (Windows, Linux, Mac)
• Converts USB to RS485, allowing communication with multiple RS485 devices on a bus
• Supports multi-drop RS485 networks (up to 32 nodes)
• Automatic send/receive control without the need for external flow control circuits
• Plug-and-play via USB with no external power required
• Compact and lightweight design
