: This is the most widely cited and used library for the Pro Micro. Since SparkFun originally designed the Pro Micro, their library includes the most accurate footprints and schematic symbols. arduino+pro+micro+eagle+library

The Pro Micro has two ground pins and two VCC pins. If you use a polygon pour (copper area) for GND, Eagle will connect all GND pins automatically. However, the pin is NOT VCC. RAW is for battery input (up to 12V). Do not connect RAW to 5V unless you want to fry the voltage regulator. The serial monitor spat out: System Ready

If you want to learn, or if you have a generic clone that doesn't match the SparkFun footprint exactly, creating your own library is a valuable skill. Since SparkFun originally designed the Pro Micro, their

To find and use an Arduino Pro Micro library in Autodesk EAGLE, the most reliable approach is to SparkFun-Eagle-Libraries or dedicated community-contributed files

Tonight, the kingdom was in peril.

While Arduino focuses on the Uno and Mega, their official "Hardware" repository contains updated libraries for the Leonardo (which shares the 32U4 core). You can derive the Pro Micro from these files with minor tweaks.
