I have a 6V motor attached to a HiLetgo Module L298N Dual H Bridge and controlled via two Raspberry Pi 3B GPIO pins (current just using HIGH & LOW).
If I use a 5V power supply from my Raspberry USB port it works perfectly.
If I attempt to power the L298N from 4 x AA batteries it doesn't (the batteries are new duracell AAs).
The power L298N LED is on but the motor does not move when I set the GPIO pins (one HIGH, one LOW).
If I connect the 4 x AA batteries directly to the motor it works.
The voltage from the batteries are reading about 5.87V and a constant current of 55mA. The USB is showing about 4.8V and a current of 44mA when idle and about 65mA when the mottor is running.
The L298N bridge has 5V terminal and a 12V terminal (same results with both)
Will the L298N ONLY work with these voltages? (the description on Amazon says it works up to 46V so I assume not).
I was hoping to eventually run 4 motors via 2 L298N bridges using PWM via a PCA9685, ideally all motors powered from 4 AA batteries, but so far I can't get 1 motor to work.
Can anyone suggest a reason why the 4 x AA batteries don't work via a L298N bridge or another way to power my motors?
