Questions
How big is the Buzz PCB?
It measures 58.4 × 85.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Buzz use?
61 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 Buzz KiCad files?
From the rabidaudio/effects repository on GitHub, at the commit this page was made from: the board is dist/buzz/buzz.kicad_pcb and its schematic ab-pedal/ab-pedal.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Buzz design in my own project?
Its repository states no licence, so its author keeps all rights: ask rabidaudio before reusing the design.
