Questions
How big is the Skeleton68 PCB?
It measures 336.6 × 121.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Skeleton68 use?
224 parts, built around the ATMEGA32U4-MU and PRTR5V0U2X. 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 Skeleton68 KiCad files?
From the skeletonkbd/Skeleton68 repository on GitHub, at the commit this page was made from: the board is Skeleton68_backlit/Skeleton68.kicad_pcb and its schematic Skeleton68_backlit/Skeleton68.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Skeleton68 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
