Questions
How big is the Wled controller PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wled controller use?
85 parts, built around the 74AHCT125D, ESP32-WROOM-32, AMS1117-3.3 and ULN2803A. 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 andreashergert1984/wled-controller repository on GitHub, at the commit this page was made from: the board is WLED Controller.kicad_pcb and its schematic WLED Controller.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 states no licence, so its author keeps all rights: ask andreashergert1984 before reusing the design.
