DRV2624 ERM, LRA haptic driver evaluation kit

1

Getting Started

The DRV2624 can be used as a demonstration or evaluation tool. When the DRV2624EVM-CT evaluation
module is powered on for the first time, a demo application automatically starts. To power the board,
connect the DRV2624EVM-CT to an available USB port on your computer using the included micro-USB
cable. The demo begins with a board power-up sequence and then enters the demo effects mode. The
four larger buttons on the wheel (1–4) can be used to sample haptic effects using both the ERM and LRA
motor in the top right corner.
