Questions
How big is the Casper PCB?
It measures 56 × 104 mm and has 2 copper layers, 1.59 mm thick.
What parts does the Casper use?
12 parts, built around the DMG2305UX. 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 Casper KiCad files?
From the nirans2002/kicad_pcb repository on GitHub, at the commit this page was made from: the board is casper/casper.kicad_pcb and its schematic casper/casper.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Casper design in my own project?
Its repository states no licence, so its author keeps all rights: ask nirans2002 before reusing the design.
