Questions
How big is the PicoWS2812 PCB?
It measures 57.4 × 62 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PicoWS2812 use?
30 parts, built around the 74HCT245. 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 PicoWS2812 KiCad files?
From the ErichStyger/mcuoneclipse repository on GitHub, at the commit this page was made from: the board is KiCAD/Projects/PicoWS2812B/PicoWS2812.kicad_pcb and its schematic KiCAD/Projects/PicoLink/PicoLink.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PicoWS2812 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ErichStyger before reusing the design.
