Questions
How big is the ButtonBd2 PCB?
It measures 103.5 × 48.3 mm and has 4 copper layers, 1.68 mm thick.
What parts does the ButtonBd2 use?
165 parts, built around the MCP2542FD-E/SN, MCP1727-3302E/SN, BAV99 and B10. 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 ButtonBd2 KiCad files?
From the frc971/electrical repository on GitHub, at the commit this page was made from: the board is circuit-boards/driver-station/ButtonBd2-v2/ButtonBd2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ButtonBd2 design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
