Before we dive into the EAGLE software, let’s clarify which board we are designing for. The Pro Micro comes in two major variants:
Most hobbyists use standard 0.1" (2.54mm) spaced male headers. The standard SparkFun library device assumes this configuration.
If you are an Autodesk EAGLE user, you have likely searched for a reliable . While the standard Arduino libraries are readily available, the Pro Micro—originally produced by SparkFun—is often missing from default installations.
Autodesk does not ship a default Pro Micro library with EAGLE. You have three primary sources.
The most common mistake users make is searching for an "Arduino" branded library for the Pro Micro. While Arduino manufactures many boards, the "Pro Micro" design is heavily associated with .
