MAX485 TTL to RS485 Converter Module

Description

MAX485 TTL to RS-485 Converter Module
The MAX485 TTL converter module is a half-duplex transceiver board designed to translate standard Transistor-Transistor Logic (TTL) serial signals from a microcontroller into differential RS-485 signals. Driven by the industry-standard MAX485 IC, this module allows microcontrollers to communicate reliably over long distances (up to 1200 meters) in noisy electrical environments using a single twisted-pair cable.
