Questions
How big is the LED PCB?
It measures 70 × 70 mm and has 2 copper layers, 1.2 mm thick.
What parts does the LED use?
39 parts, built around the ESP32-S3-MINI-1-N4R2, MD8942, ICS-43434 and DY-IRMHF384-T05-2.5KB. 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 LED KiCad files?
From the evansj/ESP32-LED repository on GitHub, at the commit this page was made from: the board is PCB/LEDC/LED.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
