> GPIOs can be extended on them via USB
Again, I am designing a farming robot. We absolutely do not want to use USB for anything critical (which is pretty much everything). On our raspberry pi motherboard I’m using SPI to talk to CAN bus chips to do motor control. I’ve had so many weird control USB issues in my life I would absolutely not want to use USB for motor control!
