Shaped LED boards inspired by films: stars, ghosts, cats, rockets, gears, moons, saucers and shields, each in its own colour. KiCad 10, JLCPCB-ready, CERN-OHL-S-2.0.
Every board is its own silhouette and solder-mask colour, with addressable RGB LEDs (XL-2020RGBC-2812B, WS2812B-2020 class) following its outline, a CH32V003 RISC-V controller running at 5 V (so it drives the LEDs directly), a MODE button, a 1-wire SWIO programming header, a 3-pin OUT header that chains the light onto the next board, and USB-C power on a tab at the bottom. 4 layers.

Questions
How big is the Art big paw PCB?
It measures 85.1 × 87.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Art big paw use?
48 parts, built around the CH32V003F4P6, XL-2020RGBC-2812B, CL21A106KAYNNNE and TS-1187A-B-A-B. 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 Art big paw KiCad files?
From the HeyPCB/led-art repository on GitHub, at the commit this page was made from: the board is boards/big-paw/kicad/art_big_paw.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Art big paw 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).
