The Arduino Pro Micro is a popular microcontroller board known for its compact size, low power consumption, and ease of use. As a designer or engineer, you may frequently incorporate the Pro Micro into your projects, and using a custom library in Eagle can greatly simplify your workflow. In this article, we'll guide you through creating an Arduino Pro Micro library for Eagle, making it easy to add this versatile board to your designs.
Once you have downloaded the .lbr file, follow these steps to use it in your project:

A proper Eagle library must include:
However, if you want the bootloader and USB interface but don't want the physical Pro Micro board, consider using the "Teensy 2.0" library (similar pinout) or designing with the "Arduino Leonardo Core" library. For 99% of users, the SparkFun Pro Micro library is the correct choice.
