Questions
How big is the PWM PCB?
It measures 70 × 65.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PWM use?
15 parts, built around the LM358 and IRF3205. 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 KiCad files?
From the HagerAzmy/KiCad_Projects repository on GitHub, at the commit this page was made from: the board is Project-1/PCB/PWM.kicad_pcb and its schematic Project-1/Schematic/PWM.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PWM design in my own project?
Its repository states no licence, so its author keeps all rights: ask HagerAzmy before reusing the design.
