DRV8843EVM

TEXAS INSTRUMENTS  DRV8843EVM  评估模块, 用于DRV8843

The is an evaluation module for DRV8843, 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 plus software/GUI supports signalling and control and PWM speed control. With the evaluation module, designers can quickly and easily evaluate the performance of DRV8843 motor driver in their specific application.
