Questions
How big is the Quad PCB?
It measures 109.6 × 107.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Quad use?
21 parts, built around the ATMEGA256RFR2-ZU, ICM-20602 and SI2318DS. 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 Quad KiCad files?
From the mrpossoms/pcb-quad repository on GitHub, at the commit this page was made from: the board is quad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Quad design in my own project?
Its repository states no licence, so its author keeps all rights: ask mrpossoms before reusing the design.
