Questions
How big is the 5way cv switch PCB?
It measures 29 × 22 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 5way cv switch use?
20 parts, built around the LMV321IDBVR, HT7550-1 and 1N4148W. 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 5way cv switch KiCad files?
From the cycfi/5way_cv_switch repository on GitHub, at the commit this page was made from: the board is 5way_cv_switch.kicad_pcb and its schematic 5way_cv_switch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 5way cv switch design in my own project?
Its repository states no licence, so its author keeps all rights: ask cycfi before reusing the design.
