Questions
How big is the PWMGenerator BrodyLaxton PCB?
It measures 124.5 × 63.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PWMGenerator BrodyLaxton use?
30 parts, built around the LM339 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 BrodyLaxton KiCad files?
From the BrodyLaxton/pcb-project repository on GitHub, at the commit this page was made from: the board is PWMGenerator-BrodyLaxton/PWMGenerator-BrodyLaxton.kicad_pcb and its schematic PWMGenerator-BrodyLaxton/PWMGenerator-BrodyLaxton.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PWMGenerator BrodyLaxton design in my own project?
Its repository states no licence, so its author keeps all rights: ask BrodyLaxton before reusing the design.
