Questions
How big is the April proj PCB?
It measures 48.5 × 62.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the April proj use?
55 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 April proj KiCad files?
From the jaycordaro/74AUC-experiments repository on GitHub, at the commit this page was made from: the board is april_proj.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the April proj design in my own project?
Its repository states no licence, so its author keeps all rights: ask jaycordaro before reusing the design.
