Questions
How big is the Tiny PWM PCB?
It measures 85.1 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tiny PWM use?
19 parts, built around the ATTINY45V-10PU and IRLZ44N. 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 Tiny PWM KiCad files?
From the marceloh220/Tiny_PWM repository on GitHub, at the commit this page was made from: the board is kiCAD/Tiny_PWM.kicad_pcb and its schematic kiCAD/Tiny_PWM.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tiny PWM design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
