Stepper motor driver EVM demonstrates integrated current sensing capabilities and performance

In stock at Mouser, the Texas Instruments DRV8884EVM stepper motor driver evaluation module (EVM) demonstrates the integrated current sensing capabilities and performance of the DRV8884. The DRV8884 is a 1.0A stepper motor driver with 1/16 micro stepping and integrated current sensing. The evaluation module includes the DRV8885 to control a stepper motor. The module also houses an MSP430 microcontroller and a USB interface chip. The MSP430F2617 MCU is used to control the DRV8884 inputs. 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 signal of the device, and drive the stepper motor by issuing the step commands at the desired rate.
