Questions
How big is the Attenuverter PCB?
It measures 29 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Attenuverter use?
59 parts, built around the TL072. 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 Attenuverter KiCad files?
From the stash-s/synth-modules repository on GitHub, at the commit this page was made from: the board is attenuverter/attenuverter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Attenuverter design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
