Arduino Pro Micro Eagle Library ~repack~ Jun 2026

The (based on the ATmega32U4) is a compact, breadboard-friendly microcontroller board widely used in custom keyboards, DIY controllers, and wearable electronics. For PCB design in Autodesk EAGLE , a dedicated library provides the schematic symbol, PCB footprint, and device definition, enabling seamless integration into custom projects.

was originally developed by SparkFun, their official repository is the most trusted source. arduino pro micro eagle library
