1 Introduction
The DRV8811EVM-001 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.
1.1 Block Diagram
1.2 Power Connectors
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.
The user must apply VM according to datasheet recommended parameters.
1.3 Test Stakes
Every pin on the device has been brought out to a test stake. A label on the silkscreen identifies each
signal.
