Questions
How big is the WLEDController PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WLEDController use?
69 parts, built around the 74AHCT125D, INA219AID, AMS1117-3.3 and AOD403. 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 WLEDController KiCad files?
From the LostInCompilation/WLED-Controller-PCB repository on GitHub, at the commit this page was made from: the board is WLEDController.kicad_pcb and its schematic WLEDController.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WLEDController design in my own project?
Its repository states no licence, so its author keeps all rights: ask LostInCompilation before reusing the design.
