TTL to RS485 converter module
TTL to RS485 converter module for long-distance, noise-resistant serial communication with microcontrollers.
The TTL to RS485 Converter Module is designed to convert TTL-level UART signals into RS485 differential signals, enabling reliable long-distance and noise-immune serial communication. This module is ideal for connecting microcontrollers to RS485 networks used in industrial and automation environments.
It supports half-duplex RS485 communication and works seamlessly with popular platforms such as Arduino, ESP32, ESP8266, Raspberry Pi, and STM32. Common applications include MODBUS communication, PLC interfacing, smart energy meters, industrial sensors, and multi-drop serial networks. The compact design and simple pin interface make it easy to integrate into embedded projects.
