More shaped LED boards inspired by films: a light bulb for Edison's thousand failures, a starfighter, a submarine, a snowman, an atom, a trophy for the underdog, 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 melody PCB?
It measures 55.6 × 101.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Art melody use?
26 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 melody KiCad files?
From the HeyPCB/led-art-2 repository on GitHub, at the commit this page was made from: the board is boards/melody/kicad/art_melody.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Art melody 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).
