DFR0779

RS485 connector expansion shield for LattePanda Alpha&Delta. This industrial-grade RS485 shield specially designed to expand two parallel RS485 ports (terminal) with high reliability for LattePanda Alpha and LattePanda Delta. Employing FTDI USB to serial port chip and industrial-grade isolated transceiver module, the shield comes with the characteristics of signal isolation, power isolation, lightning and surge protection, transient impulse voltage resistance and bus protection so that it supports reliable data transmission and also can effectively protect LattePanda mainboard for providing a high-reliability connection for point-to-point. The product employs a stackable connection, making it able to be easily fixed onto LattePanda mainboard by copper columns without blocking the heat dissipation area of the mainboard. It can be safely applied in industrial scenarios. Facilitate the development and use of industrial-grade RS232 communication on Windows (compatible with Linux).
