MAX485 TTL to RS485 Converter Module, 5V Half-Duplex, 2.5Mbps

The MAX485 TTL to RS485 Converter Module is a 5V-powered half-duplex adapter that converts TTL logic levels to RS-485 signals for reliable serial communication. It features the MAX485 chipset with low power consumption, slew-rate limited transceivers, and a 2.5 Mbps maximum data rate. The module provides fail-safe receiver inputs, short-circuit protected drivers, and high impedance output via thermal shutdown. All pins are accessible for microcontroller control, and a 5.08 mm pitch 2-pin terminal simplifies RS-485 wiring. Typical applications include industrial automation, PLC communication, access control systems, and long-distance data transmission in electrical and monitoring systems.
