## Overview

The MAX3485 module leverages the industrial-grade MAX485ESA chip to provide reliable RS485 to TTL signal conversion with robust overvoltage protection up to +12V. Featuring real-time LED indicators for send and receive status, a built-in 120Ω termination resistor for stable long-distance communication, and high-quality tantalum capacitors for power filtering, this module is designed for seamless integration with standard 2.54mm pitch pins and includes a wiring diagram for easy setup.

## Description

1, The module uses all industrial MAX485ESA chip 2, With 485 signal overvoltage protection 3, With a signal, power LED indicator, send and receive situation panoramic view 4, With 120 ohm termination resistor strobe function, long-distance communication, can be directly shorted 5, The module will be 485 signal to the MAX485 signal can withstand the common-mode voltage of -7 to +12 V, the module can be solved as a result of the 485 signal common-mode voltage is too high, resulting in 485 burn or heat problems. 6, The module uses tantalum electrolytic capacitors to filter the power supply, the power quality better. 7,The module pin pin can be directly inserted in the hole plate 2.54 pitch for easy development 8, Our all modules have to undergo a rigorous test to ensure quality 9, The back of the module with a wiring diagram, to facilitate your use  Package Included: 1xRS485 to TTL Signal Mutual Conversion Module
