Questions
How big is the CV buffer PCB?
It measures 37.7 × 36.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CV buffer use?
18 parts, built around the TL072. 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 CV buffer KiCad files?
From the blthree/synth_schematics repository on GitHub, at the commit this page was made from: the board is CV buffer/CV buffer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CV buffer design in my own project?
Its repository states no licence, so its author keeps all rights: ask blthree before reusing the design.
