Questions
How big is the Qingpi PCB?
It measures 45.6 × 82.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Qingpi use?
53 parts, built around the RP2040, W25Q16JVUXIQ, AD8403ARUZ1-REEL and ADG801BRTZ-REEL7. 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 Qingpi KiCad files?
From the u1f992/qingpi repository on GitHub, at the commit this page was made from: the board is pcb/pcb.kicad_pcb and its schematic flex/flex_xl/flex_xl.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Qingpi design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
