Questions
How big is the NomiStar PCB?
It measures 70.9 × 67.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NomiStar use?
28 parts, built around the HT7833. 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 NomiStar KiCad files?
From the Gregstr05/NomiStar repository on GitHub, at the commit this page was made from: the board is NomiStar/NomiStar.kicad_pcb and its schematic NomiStar/NomiStar.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NomiStar design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
