DFRobot (DFR0778) Expansion Shield, RS232 Connector

Product InformationAccessory Type: Alpha & Delta RS232 Expansion BoardFor Use With: Arduino BoardProduct Range: -Product OverviewRS232 connector expansion shield for LattePanda alpha & delta. Thisindustrial-grade RS-232 shield specially designed to expand one RS-232 port(D-Sub, 9Pin, male) with high reliability for LattePanda Alpha and LattePandaDelta. Employing FTDI USB to serial port chip and industrial-grade isolatedtransceiver module, the shield comes with the characteristics of signalisolation, power isolation, lightning and surge protection, transient impulsevoltage resistance and bus protection so that it supports reliable datatransmission and also can effectively protect LattePanda mainboard for providinga high-reliability connection for point-to-point. The product employs astackable connection, making it able to be easily fixed onto LattePandamainboard by copper columns without blocking the heat dissipation area of themainboard. It can be safely applied in industrial scenarios. Facilitate thedevelopment and use of industrial-grade RS232 communication on Windows(compatible with Linux).Signal & power isolationReliable transmissionUp to 115200bps communication baud rateEasy to connect and useNo effect on the cooling performance of mainboardDB9 adapter and copper columns and screws5V operating voltageOperating temperature range-40 C to +85 C2500VDC isolation voltageEIA/TIA-232-F standard compliant and not support hot plugging
