Questions

How big is the Thumbinator PCB?

It measures 44.3 × 20 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Thumbinator use?

44 parts. 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 Thumbinator KiCad files?

From the kbeckmann/thumbinator-hw repository on GitHub, at the commit this page was made from: the board is rev2/thumbinator.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Thumbinator 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).
