Questions
How big is the Wled PCB?
It measures 97 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wled use?
14 parts, built around the WEMOS D1 MINI. 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 KiCad files?
From the NightMeer/WLED-PCB repository on GitHub, at the commit this page was made from: the board is Wled.kicad_pcb and its schematic Wled.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wled design in my own project?
Its repository states no licence, so its author keeps all rights: ask NightMeer before reusing the design.
