Questions

How big is the BitSwitch SwitchBoard PCB?

It measures 116.3 × 18 mm and has 2 copper layers, 1.6 mm thick.

What parts does the BitSwitch SwitchBoard use?

23 parts, built around the 74HC165D. 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 BitSwitch SwitchBoard KiCad files?

From the emab123/BitSwitch repository on GitHub, at the commit this page was made from: the board is BitSwitch_SwitchBoard/BitSwitch_SwitchBoard.kicad_pcb and its schematic BitSwitch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the BitSwitch SwitchBoard design in my own project?

Its repository states no licence, so its author keeps all rights: ask emab123 before reusing the design.
