Questions
How big is the Vfo PCB?
It measures 41 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vfo use?
45 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 Vfo KiCad files?
From the xxv/modular-vco repository on GitHub, at the commit this page was made from: the board is board/vfo.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vfo design in my own project?
Its repository states no licence, so its author keeps all rights: ask xxv before reusing the design.
