Questions
How big is the PWM PCB?
It measures 53.5 × 52 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PWM use?
36 parts, built around the TL082CDT, LM311DRG, 1N4148W-7-F-CN and SS34. 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 francibat/academic-projects-electronics repository on GitHub, at the commit this page was made from: the board is Progetto_di_circtuiti_elettronici/Kicad/PWM/PWM/PWM.kicad_pcb and its schematic Progetto_di_circtuiti_elettronici/Kicad/PWM/PWM/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 francibat before reusing the design.
