MAX485 TTL to RS485 Converter Module

Product Description

Reliable Long-Distance Serial Communication

Long cable runs can make TTL serial communication vulnerable to electrical noise, signal degradation, and data errors. The MAX485 TTL to RS485 Converter Module provides a practical solution by converting TTL serial signals to robust RS485 differential signaling, helping maintain reliable communication between devices over much longer distances.

Built around the MAX485 chip, this compact RS485 converter module is ideal for Arduino projects, embedded systems, industrial automation, instrumentation, and other applications that require dependable serial communication. With a communication range of up to 1200 meters under suitable conditions, it helps you connect devices across extended cable runs while providing improved resistance to electrical interference.

The onboard screw terminals make RS485 wiring simple and secure, while the 2.54 mm TTL pin header allows convenient connection to compatible development boards and circuits.
