Following tutorial on main gprs shield link here, ive succesfully compiled the following code to arduino. For all the relay in our bazaar, please click bazaar relay tag to check. The relay shield provides four high quality relay that can control high current loads to arduino seeeduino boards. This will prevent the relay shield from making contact. The relay shield is an arduino compatible smart module with 4 mechanical relays providing an easy way to control high voltage. The 4a motor shield can drive two dc motors or one stepper motors, also we have the brushless motor shield to drive the brushless motor. The shield has four relays that are controlled by pins d3, d4, d5 and d6 on the particle device.

Grove relay can handle the current up to 5a at 250vac for long periods of time. Please visit our wiki page for more info about this. With the xbee form socket and 315433mhz rf module interface. I have arduino leonardo and seeedstudio gprs shield v2. Each relay is triggered via a npn transistor that takes a control signal from the particle device and switches the relay coil on and off, which in turn makes or breaks the electrical contact on the output. Shop relay shield at seeed studio, we offer wide selection of electronic modules. View pdf data sheet data sheet quad relay shield v2.
