Questions

How big is the Closet LED PCB?

It measures 33.5 × 45.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Closet LED use?

16 parts, built around the AO3400A. 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 Closet LED KiCad files?

From the CodenameUsama/Personal-Projects repository on GitHub, at the commit this page was made from: the board is Door_LED/KiCAD/Closet_LED.kicad_pcb and its schematic Door_LED/KiCAD/Closet_LED.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Closet LED design in my own project?

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