Questions
What parts does the Audio chain use?
26 parts, built around the LM2902AWYDT. 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 chain KiCad files?
From the moonbeam87/audio_chain repository on GitHub, at the commit this page was made from: the board is audio chain.kicad_pcb and its schematic audio chain.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Audio chain design in my own project?
Its repository states no licence, so its author keeps all rights: ask moonbeam87 before reusing the design.
