[DFR0144] Relay Shield for Arduino V2.1
Relay Shield for Arduino V2.1 is a completely new design which is capable of controlling 4 relays at a time. The max switching power DC 90W or AC 360VA gives direct control by Arduino/DFRduino controllers through digital I/Os with external 9V supply. With built-in Xbee socket, it can be wireless remote controlled via Xbee/bluetooth/WPM.
