The DRV8421xEVM allows for easy evaluating of the DRV8421 dual H-bridge motor driver. The evaluation module (EVM) can support the DGQ and DFU packages of the DRV8421A and DRV8421B device variants. However, only one variant and package can be populated at a time since the input control signals (MCU Ctrl 1 and MCU Ctrl 2) are shared among the devices.
The DRV8421xEVM can drive one or two brushed-DC motors, or a single bipolar stepper motor. The two onboard potentiometers provide a convenient way to manually adjust speed and direction on the fly, an excellent choice for prototyping and evaluating new designs.
