• Dual Relay Board Kit


Once assembled, the Dual Relay Board Kit allows you to control two high-power devices up to 8A each via the included mechanical relays.  The Dual Relay Board can be used to turn lights, fans and motors on/off while keeping them isolated from the microcontroller.  Independent control of each relay is provided via a 2 x 3 header making it friendly with servo cables and providing a convenient connection to many development boards. LEDs indicate relay status.


  • Comes as a kit providing lower cost
  • Control two high-power devices with one kit
  • Provides isolation between microcontroller and device being controlled
  • Easy screw terminals for relay contact and power connections
  • 3-pin servo style headers for easy connection using standard servo cables
  • LED indicators provide status of each relay
