Questions
How big is the Dnd keeb PCB?
It measures 57.2 × 94.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dnd keeb use?
30 parts, built around the ATMEGA4809-AF and AP2112K-3.3. 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 Dnd keeb KiCad files?
From the a5huynh/embedded repository on GitHub, at the commit this page was made from: the board is dnd_keeb/pcb/dnd_keeb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dnd keeb design in my own project?
Its repository states no licence, so its author keeps all rights: ask a5huynh before reusing the design.
