Questions
How big is the Pixels PCB?
It measures 330 × 350 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pixels use?
1,056 parts, built around the TPS25810RVCR and WS2812B-B/T. 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 Pixels KiCad files?
From the eurovibes/pixels repository on GitHub, at the commit this page was made from: the board is pixels.kicad_pcb and its schematic 32p.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pixels design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
