Can you please provide the PCB layout files or at least the board dimensions, connectors and holes location?Many thanks

Hi,Sorry, we don't have a CAD file for this product right now

Can we use RaspberryPi instead of Arduino ?

I need to make sure that the total mass of my project remains under a certain value, so I need to know the mass of all components I plan to use

Just this motor controller, it is OK.
