Questions
How big is the Qthub PCB?
It measures 27.1 × 14.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Qthub use?
4 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 Qthub KiCad files?
From the mikeysklar/qthub repository on GitHub, at the commit this page was made from: the board is qthub.kicad_pcb and its schematic qthub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Qthub design in my own project?
Its repository states no licence, so its author keeps all rights: ask mikeysklar before reusing the design.
