Questions
How big is the Wled PCB?
It measures 37.4 × 22.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wled use?
30 parts, built around the ESP32-C3-MINI-1, AMS1117-3.3, SPH0645LM4H-B and ESD9B3.3ST5G. 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 Urie96/my-pcb repository on GitHub, at the commit this page was made from: the board is wled/wled.kicad_pcb and its schematic esp_snapclient/esp_snapclient.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 Urie96 before reusing the design.
