The MAX485 TTL to RS-485 Converter Module is a compact, high-performance serial transceiver designed to enable robust, long-distance communication for microcontrollers like Arduino, Raspberry Pi, and ESP32. By converting standard single-ended TTL logic signals into noise-immune differential RS-485 signals, this module expands the reliable transmission range of your serial network up to 1,200 meters (4,000 feet).
Operating at 5V DC, the board features an integrated MAX485 chip that supports half-duplex communication at speeds up to 2.5 Mbps, allowing up to 32 transceivers to connect to a single multi-drop bus network. With breadboard-friendly 2.54mm pitch headers, it provides a straightforward pinout for quick hardware interfacing—including dedicated Driver/Receiver Enable pins (DE/RE) for precise data direction control. This module is the ideal choice for industrial automation, Modbus networks, remote sensor arrays, and smart building automation systems exposed to high electrical interference.
