Questions
How big is the Led Controller PCB?
It measures 72.1 × 47.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Led Controller use?
101 parts, built around the ESP32-WROOM-32E, 1ED44175N01BXTSA1, MP9943AGQ-P and CSD18540Q5B. 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 Controller KiCad files?
From the Witty-Wizard/WLED-Controller repository on GitHub, at the commit this page was made from: the board is Led-Controller.kicad_pcb and its schematic Led-Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Led Controller 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).
