Introduction

This Qwiic HAT for Raspberry Pi is the quickest and easiest way to utilize SparkFun’s Qwiic ecosystem while still using that Raspberry Pi that you’ve come to know and love. This Qwiic HAT connects the I2C bus (GND, 3.3V, SDA, and SCL) on your Raspberry Pi to an array of Qwiic connectors. It also has a few important pins on the Raspberry Pi broken out for easy access. 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!
