RS485 to TTL Converter (Two Way Converter)

Overview

The RS485 to TTL Converter is a compact and reliable two-way communication module that bridges the gap between TTL-level microcontrollers (like Arduino, ESP32, STM32) and industrial RS485 networks. It enables long-distance, noise-immune data transmission up to 800 meters, making it an essential tool for industrial automation, building management systems, and multi-node sensor networks. With support for 3.3V and 5V logic, this converter integrates seamlessly into both new and existing projects.
