Questions
How big is the Cyclops PCB?
It measures 311.4 × 93.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cyclops use?
160 parts, built around the ATMEGA32U4. 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 Cyclops KiCad files?
From the westfoxtrot/cyclops_pcb repository on GitHub, at the commit this page was made from: the board is cyclops.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cyclops design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
