Questions
How big is the VCO PCB?
It measures 50 × 200 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VCO use?
90 parts, built around the TL082, BC547 and DMMT3904W. 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 VCO KiCad files?
From the telec16/modular-synth repository on GitHub, at the commit this page was made from: the board is VCO/VCO.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the VCO design in my own project?
Its repository states no licence, so its author keeps all rights: ask telec16 before reusing the design.
