2 open source boards using the u
Real designs built with the u, 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 u
What boards using the u are built for
u: common questions
Where can I find a u reference design?
Each of the 2 boards on this page is a real design using the u. 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 u use?
Most are built on STM32 (1).
How big is a typical board using the u?
The median is 228.1 × 101.9 mm, and 50% are two-layer designs.
What is the most popular open source board using the u?
By GitHub stars, McQueen by 0BitsnBytes, with 1 stars.
Can I simulate one of these boards using the u 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.
