Questions
How big is the Ad vca PCB?
It measures 102.4 × 128.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ad vca use?
77 parts, built around the PJ301M-12. 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 Ad vca KiCad files?
From the MarkOdey/ad-vca repository on GitHub, at the commit this page was made from: the board is ad-vca.kicad_pcb and its schematic ad-vca.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ad vca design in my own project?
Its repository states no licence, so its author keeps all rights: ask MarkOdey before reusing the design.
