Questions
How big is the Pwm light controller PCB?
It measures 41.5 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pwm light controller use?
3 parts, built around the ATTINY13A-PU, AMS1117-5.0 and 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 Pwm light controller KiCad files?
From the DIYLabsED/home-electronics repository on GitHub, at the commit this page was made from: the board is pwm-light-controller/hw/src/pwm-light-controller.kicad_pcb and its schematic fridge-beeper/schematic/fridge-beeper.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pwm light controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask DIYLabsED before reusing the design.
