Description for the DRV8834EVM
The DRV8834 evaluation module (EVM) demonstrates the capabilities and performance of the DRV8834 motor driver from Texas Instruments. This EVM comes with an on-board MSP430 microcontroller which has been pre-programmed with a set of useful algorithms for driving a stepper or two brushed DC motors. The graphical user interface allows control of the EVM through the user's computer via USB port. The regulated voltage for the MSP430 is provided by LP2985-33 single-channel LDO. This EVM operates on power supply voltages from 2.5V to 10.8V.
