Questions
How big is the Mk keeb PCB?
It measures 371.5 × 152.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mk keeb use?
220 parts, built around the TUSB2036VF, TPS2042D, CPG151101S11 and BAV70,215-JSM. 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 Mk keeb KiCad files?
From the elec-mk/mk-keeb repository on GitHub, at the commit this page was made from: the board is mk_keeb.kicad_pcb and its schematic keys.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mk keeb design in my own project?
Its repository states no licence, so its author keeps all rights: ask elec-mk before reusing the design.
