Questions
How big is the Audio buffer PCB?
It measures 13.2 × 10.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Audio buffer use?
9 parts, built around the NC7WZ16P6. 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 buffer KiCad files?
From the ZeroPhone/ZeroPhone-Mod-PCBs repository on GitHub, at the commit this page was made from: the board is audio_buffer/audio_buffer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Audio buffer 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).
