Questions
How big is the Sample PCB?
It measures 226 × 69 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sample use?
6 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 Sample KiCad files?
From the gonzacba17/stratum repository on GitHub, at the commit this page was made from: the board is exports_validation/sample.kicad_pcb and its schematic exports_validation/sample.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sample design in my own project?
Its repository states no licence, so its author keeps all rights: ask gonzacba17 before reusing the design.
