Questions
How big is the Vertebra PCB?
It measures 20.3 × 46.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vertebra use?
12 parts, built around the 74LS165PC. 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 Vertebra KiCad files?
From the c3dprk/split-flap repository on GitHub, at the commit this page was made from: the board is pcb/controller/vertebra.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vertebra 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).
