Questions
How big is the Cuttle2fish PCB?
It measures 22.4 × 47.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cuttle2fish use?
26 parts, built around the APA102-2020 and LP2985-33DBV. 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 Cuttle2fish KiCad files?
From the tahnok/cuttle2fish repository on GitHub, at the commit this page was made from: the board is hardware/cuttle2fish.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cuttle2fish design in my own project?
Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
