Questions
How big is the Muffy PCB?
It measures 95.5 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Muffy use?
12 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 Muffy KiCad files?
From the SummerHigh18/BUZZ repository on GitHub, at the commit this page was made from: the board is PCB/Muffy.kicad_pcb and its schematic PCB/Muffy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Muffy design in my own project?
Its repository states no licence, so its author keeps all rights: ask SummerHigh18 before reusing the design.
