Library — Arduino Pro Micro Eagle

This maps the logical pins to the physical pads.

You can select multiple pins/pads and click Connect to map them all at once.

Click Save.

Pad 27 (second RST) is often omitted in many Pro Micro layouts – check your variant. You can select multiple pins/pads and click Connect

If you prefer to create the library manually to understand the process or customize the footprint, follow these steps in Autodesk Eagle.
