Questions
How big is the Kleinpad PCB?
It measures 79 × 79 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kleinpad use?
31 parts, built around the RKJXV122400R. 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 Kleinpad KiCad files?
From the mystster/kleinpad repository on GitHub, at the commit this page was made from: the board is kleinpad.kicad_pcb and its schematic kleinpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kleinpad 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).
