Questions
How big is the PassiveVCA PCB?
It measures 42.5 × 24.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PassiveVCA use?
13 parts. 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 PassiveVCA KiCad files?
From the kaosbeat/coatlab repository on GitHub, at the commit this page was made from: the board is modules/passiveVCA/passiveVCA.kicad_pcb and its schematic modules/passiveVCA/passiveVCA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PassiveVCA design in my own project?
Its repository states no licence, so its author keeps all rights: ask kaosbeat before reusing the design.
