The Single Relay Board can be used to turn lights, fans and other devices on/off while keeping them isolated from your microcontroller. The Single Relay Board allows you to control high-power devices (up to 10 A) via the on-board relay. Control of the relay is provided via a 1 x 3 header – friendly to servo cables and convenient to connect to many development boards.

Key Features:

  • Control high-power devices up to 10 A with a simple high/low signal.
  • Provides isolation between the microcontroller and device being controlled.
  • Screw terminals for relay connections.
  • 3-pin servo-style header for power/signal interface.
  • LED indicator provides visual feedback.

Application Ideas:

  • 120 VAC brushless fan/lighting control.
  • 12 VDC automotive applications.


  • Voltage requirements: 5 VDC (Relay Power), 3.3-5 VDC (Input Signal).
  • Current requirements: ~85 mA (Relay Power).
  • Communication: Logic High/Low (3.3–5 VDC).
  • Dimensions: 1.57 x 1.06 x 0.71 in (4.0 x 2.7 x 1.8 cm).
  • Operating temp range: -13 to +158 °F (-25 to +70 °C).
