Questions
How big is the Mixer PCB?
It measures 54.4 × 47.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mixer use?
20 parts, built around the BAT54S. 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 Mixer KiCad files?
From the paulh002/Mixer repository on GitHub, at the commit this page was made from: the board is kicad/mixer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mixer 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).
