Questions
How big is the LED dimmer PCB?
It measures 41.9 × 25.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LED dimmer use?
12 parts. 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 LED dimmer KiCad files?
From the Duckle29/12v-LED-strip-dimmer repository on GitHub, at the commit this page was made from: the board is KiCAD-project-files/LED-dimmer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED dimmer design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
