Questions
How big is the Dual VCA PCB?
It measures 45.7 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dual VCA use?
76 parts, built around the TL072 and BAT48. 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 Dual VCA KiCad files?
From the JordanAceto/Dual_2164_VCA repository on GitHub, at the commit this page was made from: the board is main_pcb/kicad_docs/dual_VCA.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dual VCA design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
