The Relay Shield is an Arduino compatible smart module with 4 mechanical relays providing an easy way to control high voltage. The max switching power is 70W DC or 35V AC.

It can be directly controlled by Arduino/Seeeduino through digital IOs with external 9V supply. With the XBee form socket and 315/433MHz RF module interface, the Relay shield can be remotely controlled, making it easy to use in robotics, industry control, smart houses etc.


Note: Place 2 layers of electrical tape on the top of the Arduino's usb connector. Take care the pins on the shield should not be touched with USB connector of Arduino UNO when they are connected.



  • Arduino/Seeeduino, Arduino Mega, and Seeeduino Mega compatible
  • 4 mechanical relays with photo-coupled circuit
  • Equipped with screw holes for easy installation
  • Native Arduino/Seeeduino compatibility
  • Up to 3 relay shields can be connected
