Questions
How big is the Frogdor PCB?
It measures 367 × 108.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Frogdor use?
182 parts, built around the ATMEGA32U4-AU and SRV05-4. 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 Frogdor KiCad files?
From the swiftrax/frogdor_79 repository on GitHub, at the commit this page was made from: the board is KiCad/frogdor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Frogdor design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
