Questions
What parts does the 66-ekip use?
190 parts, built around the ATMEGA32U4-AU, AP2112K-3.3 and WS2812. 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 66-ekip KiCad files?
From the ehagerty/66-ekip repository on GitHub, at the commit this page was made from: the board is 66_ekip.kicad_pcb and its schematic 66_ekip.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 66-ekip design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
