Arduino Pro Micro Eagle Library Jun 2026

If you cannot find a trusted library, consider:

Unlike the Uno, the Pro Micro does not have consistent pin spacing. The headers are staggered (Rows A and B). If your EAGLE footprint assumes standard 0.1" grid alignment for both rows, your PCB will not fit. You need a library that specifically accounts for the offset between the two header rows.

When you open the device in the EAGLE Library Manager or add it to your schematic, you will notice that the symbol represents the physical board. The most critical decision you will make regarding the is how you intend to mount the board to your PCB.

Unlike the Uno, the Pro Micro is often used as a embedded into custom PCBs (keyboards, joysticks, macro pads). Therefore, an accurate Eagle library footprint is critical for proper header alignment and USB socket placement. If you cannot find a trusted library, consider:

Most hobbyists use standard 0.1" (2.54mm) spaced male headers. The standard SparkFun library device assumes this configuration.
