Questions

How big is the Wled pcb PCB?

It measures 90.2 × 90.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Wled pcb use?

36 parts, built around the ESP32-DEVKITC-VE and BC337. 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 pcb KiCad files?

From the bobbarnes1981/wled-controller repository on GitHub, at the commit this page was made from: the board is wled-pcb/wled-pcb.kicad_pcb and its schematic wled-pcb/wled-pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Wled pcb design in my own project?

Its repository states no licence, so its author keeps all rights: ask bobbarnes1981 before reusing the design.
