Questions
How big is the Km star PCB?
It measures 71.9 × 68.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Km star use?
22 parts. 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 Km star KiCad files?
From the KnoxMakers/Electronics repository on GitHub, at the commit this page was made from: the board is solder-kits/km-002-holiday-star/kicad/km-star.kicad_pcb and its schematic solder-kits/km-001-logo-badge/kicad files/intro-to-solder-kit-v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Km star design in my own project?
Its repository states no licence, so its author keeps all rights: ask KnoxMakers before reusing the design.
