Questions
How big is the DC MOTOR SPEED CONTROL PCB?
It measures 67 × 36.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DC MOTOR SPEED CONTROL use?
14 parts, built around the AMS1117-3.3. 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 DC MOTOR SPEED CONTROL KiCad files?
From the yashsharmasource/stm32_projects repository on GitHub, at the commit this page was made from: the board is pcb/DC_MOTOR_SPEED_CONTROL.kicad_pcb and its schematic pcb/DC_MOTOR_SPEED_CONTROL.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DC MOTOR SPEED CONTROL design in my own project?
Its repository states no licence, so its author keeps all rights: ask yashsharmasource before reusing the design.
