Questions
How big is the Design files PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Design files use?
40 parts, built around the ATMEGA32U4-AU, LMV358 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 Design files KiCad files?
From the aspro648/Arduino repository on GitHub, at the commit this page was made from: the board is Leonardo/design_files/project.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Design files design in my own project?
Its repository states no licence, so its author keeps all rights: ask aspro648 before reusing the design.
