Questions
How big is the 555 PWM PCB?
It measures 36.1 × 22.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 555 PWM use?
14 parts, built around the IRFZ44N and NE555. 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 555 PWM KiCad files?
From the sdouze/555-PWM-Controller repository on GitHub, at the commit this page was made from: the board is 555 PWM.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 555 PWM design in my own project?
Its repository states no licence, so its author keeps all rights: ask sdouze before reusing the design.
