Questions
How big is the Audio daughterboard PCB?
It measures 90 × 155 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Audio daughterboard use?
564 parts, built around the NE5532, LM1971M, CY2305SXC-1HT and CS5361-DZZ. 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 daughterboard KiCad files?
From the Jaxc/Magna repository on GitHub, at the commit this page was made from: the board is PCB/Magna/audio_daughterboard/Audio_daughterboard.kicad_pcb and its schematic PCB/Magna/AudioAdc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Audio daughterboard design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
