Questions
How big is the Leonardo Rev3d PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Leonardo Rev3d use?
60 parts, built around the LMV358IDGKR, LP2985-33DBVR, CG0603MLC-05E and MH2029-300Y. 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 Leonardo Rev3d KiCad files?
From the nfox18212/gunproject repository on GitHub, at the commit this page was made from: the board is lib/Leonardo_Rev3d/Leonardo_Rev3d.kicad_pcb and its schematic guncontroller/guncontroller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Leonardo Rev3d 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).
