Evaluation Module for DRV8841


Order now


The DRV8841 evaluation module consists of a 2.5A, dual-H-bridge motor driver with a PWM control interface and a small number external components that can be used to drive either two brushed DC motors, a single bipolar stepper motor, or four solenoids. The on-board MSP430 MCU + software/GUI supports signaling and control and PWM speed control. With the DRV8841EVM, designers can quickly and easily evaluate the performance of DRV8841 motor driver in their specific application.
