Questions
How big is the EnlightChildLed PCB?
It measures 78.7 × 96.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EnlightChildLed use?
83 parts, built around the AP131-33WG and 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 EnlightChildLed KiCad files?
From the ribbley/enlightChildLed repository on GitHub, at the commit this page was made from: the board is pcb/enlightChildLed.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EnlightChildLed 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).
