MAX485 TTL To RS485 Converter

The MAX485 TTL to RS485 Converter Module is a compact and efficient transceiver board that converts TTL-level serial signals to RS485 for long-distance and reliable communication.
Built around the MAX485 IC, this module enables robust data transfer over distances of up to 1.2 km (4000 ft), supporting up to 32 devices on the same data line in a multi-drop configuration.

Designed for industrial and office environments, the MAX485 module offers low power consumption, high noise immunity, and error-free differential signaling — making it ideal for Arduino, microcontroller projects, and industrial control systems.
It’s the perfect solution for extending serial communication between devices in noisy or distant environments.
