SparkleButton
Designed as a WS2812b/"Neopixel" push button. Uses two (linked) tactile momentary switches, a WS2812b pixel and 0.1uF capacitor. The idea is some push buttons can also act as status lights - think the power button on a console - but most off the shelf push buttons are a fixed LED colour.
Needs 5v (LED), LED signal, switch signal and GND.
3D enclosure to come soon.

Questions
How big is the SparkleButton PCB?
It measures 24 × 22 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SparkleButton use?
9 parts, built around the WS2812B. 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 SparkleButton KiCad files?
From the TemuWolverine/Circuits repository on GitHub, at the commit this page was made from: the board is SparkleButton/SparkleButton.kicad_pcb and its schematic SparkleBoard/sparkleboard5v.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SparkleButton design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
