Questions
How big is the Kyoumi PCB?
It measures 93.4 × 55.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kyoumi use?
52 parts, built around the BQ24074RGTR. 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 Kyoumi KiCad files?
From the cloudglides/kyoumi repository on GitHub, at the commit this page was made from: the board is hardware/kyoumi.kicad_pcb and its schematic hardware/kyoumi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kyoumi design in my own project?
Its repository states no licence, so its author keeps all rights: ask cloudglides before reusing the design.
