Questions
How big is the QEZ PCB?
It measures 194.3 × 79 mm and has 2 copper layers, 1.6 mm thick.
What parts does the QEZ use?
82 parts, built around the ATMEGA32U2-AU 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 QEZ KiCad files?
From the str-dst/QEZ repository on GitHub, at the commit this page was made from: the board is pcb/qez.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the QEZ design in my own project?
Its repository states no licence, so its author keeps all rights: ask str-dst before reusing the design.
