Questions
How big is the LED CTRL PCB?
It measures 31.3 × 17.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LED CTRL use?
42 parts, built around the HX3608, LM555CMM, ME4212BM6G and ME6215C33M5G. 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 CTRL KiCad files?
From the PackageLAN/LED_DRV repository on GitHub, at the commit this page was made from: the board is LED_CTRL/LED_CTRL.kicad_pcb and its schematic LED_CTRL/LED_CTRL.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED CTRL design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
