9 open source boards using the Arduino Pro Micro
Real designs built with the Arduino Pro Micro, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

Microcontrollers on boards using the Arduino Pro Micro
What boards using the Arduino Pro Micro are built for
Arduino Pro Micro: common questions
Where can I find a Arduino Pro Micro reference design?
Each of the 9 boards on this page is a real design using the Arduino Pro Micro. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the Arduino Pro Micro use?
Most are built on AVR/Arduino (9).
How big is a typical board using the Arduino Pro Micro?
The median is 85.2 × 92 mm, and 100% are two-layer designs.
What is the most popular open source board using the Arduino Pro Micro?
By GitHub stars, For science by peej, with 100 stars.
Can I simulate one of these boards using the Arduino Pro Micro before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
