The PhidgetStepper Bipolar HC is a powerful stepper motor driver that operates on 10-30V DC and provides up to 4 amps of continuous current per phase to a single bipolar stepper motor. This controller features two operating modes: Step Mode and Run Mode. In Step Mode, users set a Target Position, and the controller intelligently moves the motor toward the target while adhering to the user-specified Acceleration and Velocity Limit. In Run Mode, the controller continuously rotates the motor in the chosen direction, again following the defined Acceleration and Velocity Limit. There are several built-in safety features, including over-current protection and polarity protection. The PhidgetStepper Bipolar HC connects directly to a computer via USB.
