Questions
How big is the Vcf PCB?
It measures 99.1 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vcf use?
80 parts, built around the TL072 and AS3320. 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 Vcf KiCad files?
From the eblade/synth repository on GitHub, at the commit this page was made from: the board is vcf/vcf/vcf.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vcf design in my own project?
Its repository states no licence, so its author keeps all rights: ask eblade before reusing the design.
