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.
