Questions
How big is the Keeb PCB?
It measures 310 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keeb use?
158 parts, built around the ATMEGA32U4-AU and 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 Keeb KiCad files?
From the sphawes/keeb repository on GitHub, at the commit this page was made from: the board is keeb.kicad_pcb and its schematic keeb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keeb design in my own project?
Its repository states no licence, so its author keeps all rights: ask sphawes before reusing the design.
