Questions
How big is the Rudolph led driver PCB?
It measures 96 × 23 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rudolph led driver use?
34 parts, built around the BD49K33G-TL, LP2980-ADJDBV, 2SC1815 and S8050. 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 Rudolph led driver KiCad files?
From the electricant/rudolph_led_driver repository on GitHub, at the commit this page was made from: the board is rudolph_led_driver.kicad_pcb and its schematic rudolph_led_driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rudolph led driver design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
