Questions
How big is the Audio PCB?
It measures 30 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Audio use?
27 parts, built around the SGTL5000XNLA3, MIC5504-1.8YM5-TR, MIC5504-3.3YM5 and SPH8878LR5H-1. 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 KiCad files?
From the ArgonautGit/kicad-projects repository on GitHub, at the commit this page was made from: the board is audio/audio.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Audio design in my own project?
Its repository states no licence, so its author keeps all rights: ask ArgonautGit before reusing the design.
