Questions
How big is the QCamPCR PCB?
It measures 82.5 × 140 mm and has 2 copper layers, 1.6 mm thick.
What parts does the QCamPCR use?
113 parts, built around the CP2104EK, ESP32-S2-WROVER-I(4M), AP63205WU and SRV05-4. 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 QCamPCR KiCad files?
From the GaudiLabs/qPocketPCR repository on GitHub, at the commit this page was made from: the board is Electronics/qCamPCB/qCamPCR.kicad_pcb and its schematic Electronics/LaserLid/LaserLid/LaserLid.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the QCamPCR 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).
