Questions
How big is the -2-- PCB?
It measures 70 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the -2-- use?
9 parts, built around the WS2812B. 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 -2-- KiCad files?
From the nasu8151/-2-- repository on GitHub, at the commit this page was made from: the board is 芝生祭高2企画コントローラー基板/芝生祭高2企画コントローラー基板.kicad_pcb and its schematic ufo/ufo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the -2-- design in my own project?
Its repository states no licence, so its author keeps all rights: ask nasu8151 before reusing the design.
