I have a question about using the Rover 5 motor driver board. I understand that the VCC power supply must be connected before connecting the Vbat line to avoid burning out components. I'd like to have only a single power switch; I'd like to have the microcontroller first supply VCC with power and then supply Vbat with power. How could I do this? Which components could I use that would use the least power while the device is running?
Another side question: How much currect does VCC typically draw? Would i be able to hook it up directly to an IO pin on the microcontroller?
VCC is likely the 5v logic supply, while Vbat is probably for the motor supply. I would imagine a solid state relay fed by VCC for control and controlling the VBAT line would work. It is expensive partwise, but, costs no uC pins.

I believe you are correct about the purposes of the supplies. Is there such a thing as a switch that uses no power while on or off and only uses power during a state transition?
