DRV8881EEVM, Evaluation Module is a platform revolving around the DRV8881E medium voltage, dual H-bridge driver and highly-configurable power stage. This device has been optimized to drive a single bipolar stepper with up to 512 degrees of externally generated Micro-Stepping. The EVM houses an MSP430 microcontroller and an USB interface chip. The USB chip allows for serial communications from a PC computer where a Microsoft Windows application is used to schedule serial commands. These commands can be used to control each of the device's signals and drive the stepper motor by issuing the step commands at the desired rate
