Questions
How big is the WS2811 3W PCB?
It measures 40 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WS2811 3W use?
53 parts, built around the MAX485ED, BP1808 and WS2811. 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 WS2811 3W KiCad files?
From the Techbeard/RS485_WS2811_10W repository on GitHub, at the commit this page was made from: the board is Controller/WS2811_3W.kicad_pcb and its schematic BodgePCB/BodgePCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WS2811 3W design in my own project?
Its repository states no licence, so its author keeps all rights: ask Techbeard before reusing the design.
