Questions
How big is the AudioMixer PCB?
It measures 80.8 × 48.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AudioMixer use?
59 parts, built around the TLV9064ID, LM358, LM4808M and MMBT3904. 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 AudioMixer KiCad files?
From the ThomLalcte/AudioMixer repository on GitHub, at the commit this page was made from: the board is AudioMixer.kicad_pcb and its schematic AudioMixer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AudioMixer design in my own project?
Its repository states no licence, so its author keeps all rights: ask ThomLalcte before reusing the design.
