Product description: Pololu VNH3SP30 - single-channel driver for MD01B 16V / 9A motors
The module with a single-channel H bridge VNH3SP30 by ST allows you to control motors powered with a voltage in the range of 5.5 V - 16 V with a continuous current consumption up to 9 A, instantaneous up to 30 A. The system allows you tochange thedirection of rotation of the motor and adjust the speed by means of a PWM signal.
