Questions
How big is the Windows PCB?
It measures 70 × 45 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Windows use?
54 parts, built around the GAQY221S, BM04B-SRSS-TB(LF)(SN) and SP0503BAHTG. 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 Windows KiCad files?
From the marmbrus/circuits repository on GitHub, at the commit this page was made from: the board is windows/windows.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Windows design in my own project?
Its repository states no licence, so its author keeps all rights: ask marmbrus before reusing the design.
