Gravity: RS485 IO Expansion Shield for Arduino Category_Motor & Servo Controllers/Motor Controllers It can be changed toOur IO expansion board is evolving, the RS485 IO Expansion Shield is now supporting Xbee and has color coded pin header. It combines our popular Xbee shield with IO expansion shield. It even supports SD module card which provides the ultimate functional expansion for Arduino so far. As its predecessor, it supports RS485, APC220 Radio Communication Module , Bluetooth, Xbee communication, servo control. ESP8266 Arduino Programming Tutorial DFRobot. com
