Hi, all

I use a L298n motor driver to push the Pololu motor https://www.pololu.com/product/992

When the PWM under 50 , the motor barely rotate . Is this normal? If so, Is there any motor driver can push the motor with  PWM under 50, even under 10?

Thanks.

That is nromal. You need some current to start a motor and keep it running. Try the map() function  https://www.arduino.cc/en/Reference/Map

Cant use higher amp output motor driver ?

You mean map i.e. 0~100 to 50~250?
