Questions
How big is the Vco2 PCB?
It measures 22.9 × 55.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vco2 use?
26 parts, built around the LM358, L7805 and BC548. 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 Vco2 KiCad files?
From the blthree/synth_schematics repository on GitHub, at the commit this page was made from: the board is vco2/vco2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vco2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask blthree before reusing the design.
