The DRV8811_RD customer EVM is the complete solution to evaluating the DRV8811 microstepping
bipolar stepper driver. It houses a USB link to provide easy control from a PC computer, an MSP430
microcontroller that interprets serial commands from the PC and generates control signals to the driver
device, and the DRV8811 device with access to all signals for a complete evaluation.

The DRV8811 customer EVM uses a combination of terminal blocks and test clips for the
application/monitoring of power. The only power rail the user must supply is VM for the device’s power
stage. VDD for logic levels is internally generated from the USB connection.
