L297 Stepper Motor Controller IC potentiom You can use this blowerThe L297 integrates all the control circuitry required to control bipolar and unipolar stepper motors. Used with a dual bridge driver such as the L298N forms a complete microprocessor to bipolar stepper motor interface. For example The L297, takes the signals from your microprocessor and translates them into stepping signals to send to the L298 which actually drives your stepper motor. The L298 is capable of driving up to 2A per coil. One interesting
