Questions
How big is the K Type PCB?
It measures 357.5 × 131.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the K Type use?
362 parts, built around the MK20DX256VLH7, TS3DS10224RUK and TS3USB30EDGS. 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 K Type KiCad files?
From the kiibohd/pcb repository on GitHub, at the commit this page was made from: the board is K-Type/K-Type.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the K Type design in my own project?
Its repository states no licence, so its author keeps all rights: ask kiibohd before reusing the design.
