Relay Shield for Arduino V2.1

The Relay shield for Arduino is one of the more interesting projects you can do using an Arduino is being able to control household appliance like Lamps, Fans, and water pumps. However, dealing with such requires and external circuit that can the control higher voltage, and current loads, This relay shield from DFRobot specifically allows you to do that. This relay shield allows you to control 4 different devices at once (please check the specification first). This relay shield also features an Xbee socket which allows you to attach an Xbee/Bluetooth/WiFi module to enable wireless control.

NOTE:It requires an external power supply to drive the xbee module and relays.
