MAX485 RS-485 to TTL Converter Module

The MAX485 RS-485 to TTL Converter Module is a level-shifter interface board that allows communication between RS-485 differential bus systems and TTL serial devices such as microcontrollers. It uses the MAX485 transceiver IC to convert between RS-485 differential signals and standard UART TTL signals. This module supports half-duplex communication and is suitable for long-distance and noise-resistant serial networks.

This converter module is ideal for industrial control, automation systems, sensor networks, and multi-node serial communication projects requiring robust differential signaling over twisted pair cabling.
