Questions
How big is the Knipper PCB?
It measures 100 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Knipper use?
35 parts, built around the LTV-814, NE555 and IRF5210PBF. 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 Knipper KiCad files?
From the jrv/knipper repository on GitHub, at the commit this page was made from: the board is knipper.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Knipper design in my own project?
Its repository states no licence, so its author keeps all rights: ask jrv before reusing the design.
