Questions
How big is the Assembly PCB?
It measures 254 × 254.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Assembly use?
236 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 Assembly KiCad files?
From the K-0hm/Chessboard repository on GitHub, at the commit this page was made from: the board is jlcpcb/assembly/assembly.kicad_pcb and its schematic Kicad_v_plein/Leds.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Assembly 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).
