Qwiic Shield for Arduino & Photon Hookup Guide
The Qwiic Shield (for Arduino or Particle Photon) is the first step in getting acquainted with SparkFun’s Qwiic connect ecosystem. It connects the I2C bus (GND, 3.3V, SDA, and SCL) on your Arduino or Photon board to a series of SparkFun Qwiic connectors. The board already has the circuitry to convert the 5V given to the 3.3V required by I2C boards in our Qwiic ecosystem. The Arduino shield also has holes for mounting Qwiic boards. Since the Qwiic system allows for daisy chaining (as long as your devices are on different addresses) you can stack as many sensors as you’d like to create a tower of sensing power!
Here’s a quick overview of the Qwiic shield for Arduino. The Qwiic shield for Photon is similar but made for the Particle Photon’s footprint.
To follow along with this hookup guide, you will need any Arduino with the R3 header footprint, or a Photon Board. This includes the Uno, RedBoard and many other Arduino compatible boards! Here are just a few of the compatible boards.
Now you probably didn’t buy the Qwiic shield if you didn’t have any Qwiic products to use with it, right? Well, if you don’t have any Qwiic products, the following might not be a bad place to start.
Finally, you’ll need our handy Qwiic connectors to easily connect sensors to your Qwiic shield. Below are a few options.
You will need a soldering iron, solder, and general soldering accessories to solder the header pins to the Qwiic shields.
If you aren’t familiar with our new Qwiic system, we recommend reading here for an overview. We would also recommend taking a look at the following tutorials if you aren’t familiar with them.
