2 open source boards using the U7
Real designs built with the U7, 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 U7
What boards using the U7 are built for
U7: common questions
Where can I find a U7 reference design?
Each of the 2 boards on this page is a real design using the U7. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
What parts are used alongside the U7?
The U10, U2, U4, U5 and U6 appear in the most repositories here.
Which microcontrollers do boards using the U7 use?
Most are built on STM32 (1).
How big is a typical board using the U7?
The median is 136 × 124.1 mm, and 0% are two-layer designs.
What is the most popular open source board using the U7?
By GitHub stars, Azusa by issaimaru, with 9 stars.
Can I simulate one of these boards using the U7 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.
