I did check my solder joints and power leads. Will 4 AA batteries be enough for this board?
4 X 1.5V = 6v No load, so under load when the motors are running the voltage will probably be nearer 4-5v so the on board voltage regulator will just about work at 6v but will stop functioning at 4v.
As I said these L298N boards are design to operate with a 12v motor supply, at lower voltages the volt drop across the controller chip will consume much of your battery voltage , which will lead to your motors being slow or not functioning.
