Questions
How big is the Casper 2 PCB?
It measures 60 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Casper 2 use?
17 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 2 KiCad files?
From the nirans2002/kicad_pcb repository on GitHub, at the commit this page was made from: the board is casper/casper_2.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 2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask nirans2002 before reusing the design.
