Questions
How big is the MiniKeyboard PCB?
It measures 135.9 × 106.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MiniKeyboard use?
122 parts, built around the WS2812B. 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 MiniKeyboard KiCad files?
From the DaveRichmond/PCBs repository on GitHub, at the commit this page was made from: the board is MiniKeyboard/MiniKeyboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MiniKeyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask DaveRichmond before reusing the design.
