Dual Relay Board Development Kit

This Dual Relay Board kit allows you to control household devices (up to 8A) while keeping them isolated from the microcontroller. You'll be able with this Dual Relay Board kit to turn lights, fans and motors on/off and learn about home automation.

Each relay is controlled by a 3pin header (easy to connect using a servo cable) that makes it easy to connect with the main development board such as the Board of Education Shield for Arduino or the Eddie Control Board.

LEDs indicate relay status.
