Questions
How big is the VCF PCB?
It measures 39.6 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VCF use?
106 parts, built around the LM13700M, BC857 and BC847. 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 marangisto/VCF repository on GitHub, at the commit this page was made from: the board is 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).
