i have servo motor and i have applied high voltage to it the control not working so i need and control circuit
plz i am ask about the servo motor controller circuit which in the red circle how can i made it
or if there are anther way to control dc motor
The red board in that image is supposed to be taken from an existing servo motor, such as this one.
If you do not want to do this and your motor consumes up to 12A at 6-16V, you can instead use a JRK controller board. In this case, you would not need the Sabertooth motor controller as the large DC motor controller.
