Questions
How big is the Cvbs effects PCB?
It measures 44.5 × 39.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cvbs effects use?
25 parts, built around the LM1881, LM339 and LM7805. 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 Cvbs effects KiCad files?
From the ckarcz/electronics repository on GitHub, at the commit this page was made from: the board is video/cvbs-effects/cvbs-effects.kicad_pcb and its schematic synth/eurorack-power-bus/kicad/eurorack-power-bus.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cvbs effects design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
