Questions
How big is the Quetta PCB?
It measures 87.5 × 42.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Quetta use?
83 parts, built around the CC2500RGP, MMA8452QT, BC817 and IRLML9303. 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 Quetta KiCad files?
From the Kreyl/Quetta repository on GitHub, at the commit this page was made from: the board is Quetta_hw/Quetta.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Quetta design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
