Questions

How big is the Layouts PCB?

It measures 41.9 × 35.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Layouts use?

43 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 Layouts KiCad files?

From the eigenlucy/nonhumanscent repository on GitHub, at the commit this page was made from: the board is layouts/default/default.kicad_pcb and its schematic ams1117-33/elec/layout/default/ams1117-33.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Layouts design in my own project?

Its repository states no licence, so its author keeps all rights: ask eigenlucy before reusing the design.
