Questions
How big is the Keeb2 PCB?
It measures 306.7 × 100.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keeb2 use?
160 parts, built around the ATMEGA32U4-AU. 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 Keeb2 KiCad files?
From the SimonRosee/Simax69 repository on GitHub, at the commit this page was made from: the board is v2/keeb2.kicad_pcb and its schematic v2/keeb2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keeb2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask SimonRosee before reusing the design.
