2 open source boards using the SWD
Real designs built with the SWD, 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 SWD
What boards using the SWD are built for
SWD: common questions
Where can I find a SWD reference design?
Each of the 2 boards on this page is a real design using the SWD. 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 SWD use?
Most are built on STM32 (2).
How big is a typical board using the SWD?
The median is 49.3 × 27 mm, and 100% are two-layer designs.
What is the most popular open source board using the SWD?
By GitHub stars, Ignition by cuspaceflight, with 3 stars.
Can I simulate one of these boards using the SWD 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.
