The Qwiic system is a SparkFun innovation that utilizes the I2C protocol and polarized 4-pin JST connectors to allow you to create modular circuits using any of our 100+ compatible breakout boards and microcontrollers. Not sure what that means? No worry! All you really need to know is that Qwiic eliminates the hassles of soldering hookup wire and deciphering messy hookup diagrams, making it extremely easy for even a novice to pick up an Arduino and any given sensor, and begin experimenting right away. Don’t believe me? Check out the following simple sketches utilizing SparkFun’s Qwiic Pro Micro and a handful of other breakout boards.
