Questions
How big is the Klipperzero PCB?
It measures 77 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Klipperzero use?
31 parts, built around the ME6211C33M5G-N, 1N5819WS and BSS138. 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 Klipperzero KiCad files?
From the Vyolex/klipperzero repository on GitHub, at the commit this page was made from: the board is KlipperZero.kicad_pcb and its schematic KlipperZero.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Klipperzero design in my own project?
Its repository states no licence, so its author keeps all rights: ask Vyolex before reusing the design.
