Questions
How big is the Vco3 PCB?
It measures 79.4 × 45.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vco3 use?
46 parts, built around the LM324, TL072 and BC559. 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 Vco3 KiCad files?
From the blthree/synth_schematics repository on GitHub, at the commit this page was made from: the board is vco3/vco3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vco3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask blthree before reusing the design.
