What parts does the 7seg use?
20 parts, built around the WS2812B. 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 7seg KiCad files?
From the deffener/7seg repository on GitHub, at the commit this page was made from: the board is 7seg.kicad_pcb and its schematic 7seg-stand.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 7seg design in my own project?
Its repository states no licence, so its author keeps all rights: ask deffener before reusing the design.
