Questions
How big is the MiniQ PCB?
It measures 80 × 50 mm and has 2 copper layers, 1.69 mm thick.
What parts does the MiniQ use?
111 parts, built around the RP2040, MAX-M8C-0, BMP390 and W25Q128JVSIQ. 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 MiniQ KiCad files?
From the bobtheguymk2/miniQ repository on GitHub, at the commit this page was made from: the board is Mini Q.kicad_pcb and its schematic Mini Q.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MiniQ design in my own project?
Its repository states no licence, so its author keeps all rights: ask bobtheguymk2 before reusing the design.
