DRV8846EVM

EVALUATION BOARD, STEPPER MOTOR.

The DRV8846EVM is an Evaluation Module for evaluate the operation and performance of DRV8846, a highly integrated stepper motor controller and driver. The DRV8846 has been optimized to drive a single bipolar stepper with up to 1/32 microstepping with on-chip indexers. The board incorporates a MSP430 microcontroller and an USB interface chip. The USB chip allows for serial communications from a PC computer where a 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. The microcontroller firmware operates using internal index mode.
