Questions
How big is the NiAudio PCB?
It measures 99 × 75.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NiAudio use?
104 parts, built around the TUSB2036VF, D1213A-02SR and AZ1117CH-3.3TRG1. 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 NiAudio KiCad files?
From the Szybet/niAudio repository on GitHub, at the commit this page was made from: the board is pcb-board/kicad-project/NiAudio.kicad_pcb and its schematic pcb-board/kicad-project/NiAudio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NiAudio 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).
