Questions
How big is the Wled PCB?
It measures 90.8 × 58.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wled use?
60 parts, built around the ESP32-S3-WROOM-1-N8, SN74HCT125DRE4, LM2596S-ADJ and AMS1117-3.3. 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 Shivansh21git/WLED_PCB-ESP32-S3 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 Shivansh21git before reusing the design.
