3 open source boards using the 4U7
Real designs built with the 4U7, 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.

What boards using the 4U7 are built for
4U7: common questions
Where can I find a 4U7 reference design?
Each of the 3 boards on this page is a real design using the 4U7. 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 4U7?
The 100N, 10N, 10P, 10U and 30P appear in the most repositories here.
Which microcontrollers do boards using the 4U7 use?
Most are built on STM32 (2).
How big is a typical board using the 4U7?
The median is 52 × 52 mm, and 100% are two-layer designs.
What is the most popular open source board using the 4U7?
By GitHub stars, GPS-Tracker by mohamedboubaker, with 40 stars.
Can I simulate one of these boards using the 4U7 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.
