Qwiic Quad Relay Hookup Guide
SparkFun's Qwiic Quad Relay is a product designed for switching not one but four high powered devices from your Arduino or other low powered microcontroller using I2C. It has four relays rated up to 5 Amps per channel at 250VAC or 30VDC that are controlled by an ATtiny84A. Each channel has its own blue stat LED, silk for easy identification, and screw terminals for easy connection. The product is Qwiic enabled allowing you to easily integrate the Quad Relay with other products in the Qwiic environment, which means no solder neccessary!
For the example under Hardware Assembly, I used the following materials to control a load (i.e. a lamp). You may not need everything though depending on what you have. Add it to your cart, read through the guide, and adjust the cart as necessary.
You could also use our 9 volt wall adapter if that suits your fancy and we have a number of Qwiic cable sizes to fit your needs.
You will need a flush cutter and wire stripper to remove the sheath and insulation from a cable. A Phillips head screwdriver will be required to connect the load's to a screw terminal.
If you aren't familiar with the Qwiic system, we recommend reading here for an overview.
