Questions
How big is the Vca PCB?
It measures 99.1 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vca use?
106 parts, built around the TL084 and 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 Vca KiCad files?
From the eblade/synth repository on GitHub, at the commit this page was made from: the board is vca/vca/vca.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vca design in my own project?
Its repository states no licence, so its author keeps all rights: ask eblade before reusing the design.
