Texas Instruments DRV8421BEVM Evaluation Module
Texas Instruments DRV8421BEVM Evaluation Module is a platform for evaluating the performance of the DRV8421 dual H-bridge motor driver. The DRV8421BEVM evaluates the DRV8421A and DRV8421B device variants in DGQ and DFU packages. Since the input control signals (MCU Ctrl 1 and MCU Ctrl 2) are shared among the devices, only one variant and package can be populated at a time.
The TI DRV8421BEVM drives one or two brushed-DC motors or a single bipolar stepper motor. The two onboard potentiometers offer a convenient way to manually adjust speed and direction quickly, making it an ideal choice for prototyping and evaluating designs.
