DRV8885EVM (TEXAS INSTRUMENTS)

The DRV8885EVM is a 1.5A stepper motor driver with integrated current sensing evaluation module. The DRV8885 customer EVM is a platform revolving around the DRV8885, a medium voltage dual Hbridge driver and highly configurable power stage. This device has been optimized to drive a single bipolar stepper with up to 16 degrees of internally generated microstepping. The EVM includes the DRV8885 to control a stepper motor, a MSP430F2617 to control the DRV8885 inputs and a USB to UART to communicate between the GUI and the MSP430F2617. The EVM houses an 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.
