About this item

The WeAct Studio USB to RS485 Converter Module is a robust and reliable solution for connecting USB-enabled devices to RS485 communication buses. Designed for industrial-grade applications, this module ensures stable and interference-resistant data transmission, ideal for long-distance, multi-node serial networks like building automation, industrial control, sensor monitoring, and energy systems. This module features a high-quality RS485 transceiver with automatic transmit/receive direction control, eliminating the need for manual RTS signal handling. It supports half-duplex RS485 communication with strong ESD protection and is built to tolerate harsh electrical environments. A unique feature is the switchable 120Ω termination resistor, accessible via an onboard 1kΩ/120Ω toggle switch, making network impedance matching simple and flexible. Powered via USB, the module is plug-and-play with no external power needed and is compatible with Windows, macOS, and Linux via standard CH340 or FTDI drivers (depending on the version). With a compact design and high reliability, the WeAct USB to RS485 module is perfect for both field deployment and lab development, offering stable communication across multiple RS485 nodes.
