Questions

How big is the Apus PCB?

It measures 40 × 24 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Apus use?

19 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 Apus KiCad files?

From the vionqaro/apus repository on GitHub, at the commit this page was made from: the board is Apus/Apus.kicad_pcb and its schematic Apus/Apus.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Apus design in my own project?

Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
