Questions
How big is the BetaBoard PCB?
It measures 144.8 × 204.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BetaBoard use?
40 parts, built around the ATMEGA328P-PU, 74HC04D, 74HC154D and A6T-8104. 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 BetaBoard KiCad files?
From the BetaWall/BetaBoard repository on GitHub, at the commit this page was made from: the board is KiCad/BetaBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BetaBoard design in my own project?
Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
