MT485S module, you can achieve RS485 and TTL level conversion. Module with automatic flow control function, can achieve RS485 transceiver automatically convert, users can use the same as the use of 232 serial port MT485S module, without regard to send and receive direction control, user-friendly programming and improve system stability. Features Module is 5V power supply, TTL transceiver interface compatible with 3.3V and 5.0V level. Industrial design, stable and reliable performance, signal transmission rate up to 500Kbps; The design of the module takes into account the signal integrity and EMC characteristics in particular, while adding multiple protection measures: ± 15KV ESD protection, 600W dual TVS protection, 10O current protection resistor. Support multi-machine communication, up to 128 devices can be mounted on the bus. Module hot-swappable, strong driving capability, the longest transmission distance of 1,200 meters; All single-sided alignment, to ensure signal quality, enhance signal integrity, while a large area shop copper, to prevent signal interference; With terminals and welding lead hole, user-friendly; With 3 mm screw holes for easy installation.
