Boardoza RS485 5V Transceiver Breakout Board

The Boardoza RS485 5V Transceiver Breakout Board is a robust long-distance communication interface built around the HTC Korea MAX485 RS-485 transceiver. Designed for 5V systems, this board enables stable half-duplex differential communication, making it ideal for electrically noisy environments and extended cable runs.

With its stable, high-speed, and interference-resistant communication capabilities, this module is perfectly suited for industrial automation, sensor networks, CNC systems, building management, and microcontroller-based communication projects.
