Questions
How big is the Dimmable psu PCB?
It measures 77 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dimmable psu use?
88 parts, built around the LM324, LMC7660N, TPS92640PWP and BAT54S. 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 Dimmable psu KiCad files?
From the dexterlb/led_controller repository on GitHub, at the commit this page was made from: the board is boards/standalone/dimmable_psu/dimmable_psu.kicad_pcb and its schematic boards/bundled_esp/encoder/encoder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dimmable psu design in my own project?
Its repository states no licence, so its author keeps all rights: ask dexterlb before reusing the design.
