SparkFun Qwiic Quad Solid State Relay Kit Hookup Guide
We love our Solid State Relay - 40A. We love it so much we've designed the SparkFun Qwiic Quad Solid State Relay Kit. This kit allows you to assemble up to four of these solid state relays on a single PCB and control them all via I2C from your favorite microcontroller. The Quad Solid State Relay Kit comes with four solid state relays rated up to 40A at voltages between 28-380 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.
In this tutorial we'll cover what is included with the Quad Solid State Relay Kit along with how to assemble and finally how to connect it to an Arduino and Raspberry Pi to use the examples included in our Arduino Library and Python package.
You will need a microcontroller to control the Qwiic Quad Solid State Relay in order to follow along with this tutorial. Below are a few options that come Qwiic-enabled out of the box:
We also have a Python package available for this and our other Qwiic Relay boards so you can use a Raspberry Pi as your controller as well.
If your chosen microcontroller is not already Qwiic-enabled, you can add that functionality with one or more of the following items:
You will also need at least one Qwiic cable to connect your Quad Solid State Relay Kit to your microcontroller.
While there is no soldering required to assemble the Qwiic Quad Solid State Relay, there is some minor assembly involved. You will need a screwdriver as well as wire strippers to assemble your kit and prepare your wires.
If you aren't familiar with the Qwiic system, we recommend reading here for an overview:
We would also suggest reading through the following tutorials if you are not familiar with the concepts covered in them:
