MAX485 TTL to RS485 converter module for long-distance, noise-resistant serial communication between microcontrollers and RS485 devices.
The MAX485 TTL to RS485 Converter Module provides a simple interface between TTL-level UART communication and the RS485 differential communication standard. It is commonly used to connect Arduino, ESP32, PLCs, sensors, meters and other embedded devices over RS485 networks.
The module uses the MAX485 transceiver and provides differential A/B communication lines for reliable data transmission over longer distances and in electrically noisy environments. It supports half-duplex communication and is suitable for Modbus RTU and other RS485-based communication systems.
