Questions
How big is the Bufferedmult PCB?
It measures 30 × 22.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bufferedmult use?
19 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 Bufferedmult KiCad files?
From the roryjamesallen/universal-pcb repository on GitHub, at the commit this page was made from: the board is backpack pcbs/bufferedmult/bufferedmult.kicad_pcb and its schematic backpack pcbs/attenuverter/attenuverter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bufferedmult 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).
