Questions
How big is the PwmController PCB?
It measures 70 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PwmController use?
50 parts, built around the ATMEGA328-AU, L298N, LM311 and ULN2803A. 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 PwmController KiCad files?
From the bask185/pwmController repository on GitHub, at the commit this page was made from: the board is pwmController.kicad_pcb and its schematic DCC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PwmController design in my own project?
Its repository states no licence, so its author keeps all rights: ask bask185 before reusing the design.
