Introduction
Introducing the SparkFun Qwiic Dual Solid State Relay. The Qwiic Dual Solid State Relay sports two solid state relays rated up to 25A at 240 VAC so you can switch some serious power with this board all from a single Qwiic connector attached to an Arduino or other low-powered microcontroller. The Dual Solid State Relay is the little sibling of our Qwiic Quad Solid State Relay Kit intended for users looking for a smaller solid state relay option.
