Questions
How big is the VCF PCB?
It measures 111.4 × 104.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VCF use?
133 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 VCF KiCad files?
From the MatthewATaylor/Modular-Synth-Hardware repository on GitHub, at the commit this page was made from: the board is 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 publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
