Questions
How big is the PWMGenerator mhe4 PCB?
It measures 100 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PWMGenerator mhe4 use?
30 parts, built around the LM339, 1N4005G 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 mhe4 KiCad files?
From the linuxyix/pcb_2150 repository on GitHub, at the commit this page was made from: the board is PWMGenerator_mhe4_CMPE2150/PWMGenerator-mhe4.kicad_pcb and its schematic PWMGenerator_mhe4_CMPE2150/PWMGenerator-mhe4.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PWMGenerator mhe4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask linuxyix before reusing the design.
