1 open source board using the U22
Real designs built with the U22, 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 U22
What boards using the U22 are built for
U22: common questions
Where can I find a U22 reference design?
Each of the 1 boards on this page is a real design using the U22. 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 U22 use?
Most are built on STM32 (1).
How big is a typical board using the U22?
The median is 105 × 137 mm, and 0% are two-layer designs.
What is the most popular open source board using the U22?
By GitHub stars, Azusa by issaimaru, with 9 stars.
Can I simulate one of these boards using the U22 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.
