Questions
What parts does the Standalone use?
37 parts, built around the ATMEGA328-PU, L7805 and 100UF/16V. 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 Standalone KiCad files?
From the PSRprogam/PI3 repository on GitHub, at the commit this page was made from: the board is standalone.kicad_pcb and its schematic standalone.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Standalone design in my own project?
Its repository states no licence, so its author keeps all rights: ask PSRprogam before reusing the design.
