Hardware Overview
The DRV201EVM allows evaluation of the DRV201 IC as a voice coil motor (VCM) driver for camera
autofocus. DRV201EVM has separate connections for Isource and Isink pins that can be used to connect
to any VCM actuator or VCM in a camera module. If VCM actuator is not available there are on board
mounted inductor and resistor available to model VCM.

The DRV201EVM can be configured and monitored through a Windows GUI application running on a PC.
The GUI communicates with the DRV201EVM through the USB Interface Adapter (included with EVM kit),
which acts as an I
