Questions
How big is the Qs75 PCB?
It measures 285 × 95.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Qs75 use?
287 parts, built around the PRTR5V0U2X and XC6220B331MR. 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 Qs75 KiCad files?
From the chie4hao/qs75 repository on GitHub, at the commit this page was made from: the board is qs75.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Qs75 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
