Bipolar Stepper Motor Driver Board

The FE_STEPPER_BP is a bipolar stepper driver for use in the control and sequencing of stepper motors. The driver incorporates many of the complicated functions needed to efficiently drive a stepper motor such as current chopping, microstep sequencing, and H-Bridge control. The driver has many safety features such as overheat protection, safe power up sequencing, and undervolt lock out protection. The driver has been designed to work with most popularly available stepper motors.

Please see the datasheet for full information on all of the features and capabilities of the motor driver.
