Questions
How big is the MoodBearsKB PCB?
It measures 266.4 × 94.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MoodBearsKB use?
104 parts. 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 MoodBearsKB KiCad files?
From the s-grundner/MoodBearsKB repository on GitHub, at the commit this page was made from: the board is ecad/MoodBearsKB/MoodBearsKB.kicad_pcb and its schematic ecad/MoodBearsKB/MoodBearsKB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MoodBearsKB design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
