Introduction

Heads up! This is for the Qwiic Pro Micro USB-C (ATmega32U4) version. If you are looking for information about hardware on the Pro Micros with the micro-b USB connector, make sure to check out the older Pro Micro & Fio V3 Hookup Guide.

The SparkFun Qwiic Pro Micro USB C is a really cool, little development board. It's an Arduino-compatible microcontroller, micro-sized, and it accomplishes with one single chip what old Arduino Unos, Duemilanoves, and Diecimeillas could never dream of: true USB functionality. In this tutorial, we'll check out the updated Qwiic Pro Micro and go through a few examples to get you started!
