Questions
How big is the Wled controller PCB?
It measures 20 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wled controller use?
18 parts, built around the ESP32-C3-MINI-1, TLV75533PDBV, BC847 and S3B-PH-K-S. 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 Wled controller KiCad files?
From the HarexeW/wled-controller repository on GitHub, at the commit this page was made from: the board is kicad/wled-controller.kicad_pcb and its schematic kicad/board_structure.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wled controller 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).
