Questions

How big is the Keyboard PCB?

It measures 303 × 94.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Keyboard use?

295 parts, built around the USBLC6-2SC6 and SK6812MINI-E. 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 Keyboard KiCad files?

From the BuzzBumbleBee/keyboards repository on GitHub, at the commit this page was made from: the board is 65-F072/kicad/keyboard.kicad_pcb and its schematic 65-F072/kicad/keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Keyboard 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).
