2 open source boards using the CPU
Real designs built with the CPU, 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 CPU are built for
CPU: common questions
Where can I find a CPU reference design?
Each of the 2 boards on this page is a real design using the CPU. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
How big is a typical board using the CPU?
The median is 156.1 × 119.5 mm, and 100% are two-layer designs.
What is the most popular open source board using the CPU?
By GitHub stars, SNSP-CPU-01 by stonedDiscord, with 65 stars.
Can I simulate one of these boards using the CPU 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.
