Details

The MAX485 module is a low-power transceiver designed for RS-485 and RS-422 communication, enabling reliable data transmission over long distances up to 1200 meters. It features a single 5V supply voltage with ultra-low quiescent current (120µA to 500µA) and shutdown current (0.1µA), minimizing thermal dissipation and system cost. This module contains one driver and one receiver, supporting half-duplex communication with slew-rate limiting to reduce EMI. Built-in ±15kV ESD protection ensures industrial safety and durability. Perfect for applications like industrial automation, building control, and long-range IoT networks, it bridges TTL-level microcontrollers (Arduino, ESP32, etc.) to robust RS-485 buses. Choose this module for its proven reliability, ease of integration, and compatibility with standard communication protocols.
