Questions
How big is the PWMGenerator rkroetch1 PCB?
It measures 81.8 × 65.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PWMGenerator rkroetch1 use?
30 parts, built around the 1N4005G, AS11CP and NANOSMDC016F-2. 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 PWMGenerator rkroetch1 KiCad files?
From the robertkroetch/PCB_Project repository on GitHub, at the commit this page was made from: the board is PWMGenerator-rkroetch1/PWMGenerator-rkroetch1.kicad_pcb and its schematic PWMGenerator-rkroetch1/PWMGenerator-rkroetch1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PWMGenerator rkroetch1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask robertkroetch before reusing the design.
