Perfecting Your PCB: A Guide to the Arduino Pro Micro Eagle Library
Once you have downloaded the .lbr file, follow these steps to get it into your project: arduino+pro+micro+eagle+library

The project was called Haptic Grasp v4.2 . It was her magnum opus: a myoelectric prosthetic hand for a young violinist named Chloe, who had lost her right hand below the elbow in a farming accident. The goal wasn't just a hand that could hold a bow. It was a hand that could feel the resonant vibration of a violin’s G-string through the bone of her wrist.

: This is the gold standard. It includes tested footprints for the Pro Micro and other common boards. You can download the entire collection from the SparkFun-Eagle-Libraries GitHub repository .
Elara stared at the EAGLE layout window. The board was a beautiful, terrifying jungle of dark blue traces on a light blue background. She had spent three weeks routing this thing. Three weeks of moving vias by a single mil, of agonizing over ground planes, of whispering sweet nothings to the autorouter (which she never actually used—she was a manual-routing purist).
Assuming you have Autodesk Eagle (Version 9.x or Fusion 360/Eagle), here is how to install your new library.
