Questions
How big is the Audio diver PCB?
It measures 99 × 99 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Audio diver use?
103 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 Audio diver KiCad files?
From the audio32/audio32-codec-pcb repository on GitHub, at the commit this page was made from: the board is audio-diver.kicad_pcb and its schematic audio-diver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Audio diver design in my own project?
Its repository states no licence, so its author keeps all rights: ask audio32 before reusing the design.
