Controlling power to motor driver
December 23, 2012
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?
