Questions
What parts does the Circle fifth use?
18 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 Circle fifth KiCad files?
From the sukepc0824/CycleTone repository on GitHub, at the commit this page was made from: the board is kicad/circle_fifth.kicad_pcb and its schematic kicad/circle_fifth.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Circle fifth design in my own project?
Its repository states no licence, so its author keeps all rights: ask sukepc0824 before reusing the design.
