The DRV8805 evaluation module consists of a quad low-side motor driver with built-in indexer control interface that can be used to drive a unipolar stepper motor in full-step, half-step or wave mode. With the DRV8805EVM, designers can quickly and easily evaluate the performance of DRV8805 motor driver in their specific application. This EVM comes with an on-board MSP430 microprocessor which has been pre-programmed for standalone operation. The regulated voltage for the MSP430 is provided by TPS7A4001. This EVM operates on power supply voltages from 8.2 V to 60 V.
