Questions
How big is the Stack light sub PCB?
It measures 190.4 × 8.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stack light sub use?
26 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 Stack light sub KiCad files?
From the CarterKoopa/stack_light_pcb repository on GitHub, at the commit this page was made from: the board is stack_light_sub/stack_light_sub.kicad_pcb and its schematic stack_light.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stack light sub design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
