Questions
How big is the OSFRD PCB?
It measures 201 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OSFRD use?
62 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the OSFRD KiCad files?
From the SleepUnit/CrushCounter repository on GitHub, at the commit this page was made from: the board is 1.5/OSFRD.kicad_pcb and its schematic 2.0/2.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OSFRD design in my own project?
Its repository states no licence, so its author keeps all rights: ask SleepUnit before reusing the design.
