MAX485 module - RS485 module

The MAX485 Module is a compact and efficient RS-485 communication interface board based on the MAX485 low-power transceiver IC. It is designed to enable reliable serial communication over long distances while maintaining strong resistance to electrical noise and interference.

This module converts standard TTL serial signals from microcontrollers into RS-485 differential signals, making it suitable for industrial and embedded communication systems. The onboard terminal block allows easy connection to RS-485 bus lines, while all chip control pins are accessible for flexible operation and direction control through a microcontroller.

The module operates at 5V DC and is commonly used with platforms such as Arduino, AVR, PIC, STM32, Raspberry Pi, and other embedded systems.
