DRV2603 ERM/LRA Haptic Driver Evaluation Kit
The DRV2603 is a haptic driver designed to control Linear Resonant Actuators (LRA) and Eccentric
Rotating Mass (ERM) motors. The DRV2603 provides many features which help eliminate the design
complexities of haptic motor control including reduced solution size, high efficiency output drive, simplified
control signaling, quick device startup, and auto-resonance frequency tracking.
The DRV2603EVM-CT Evaluation Module (EVM) is a complete demo and evaluation platform for the
DRV2603. The kit includes a microcontroller, linear actuator, eccentric rotating mass motor, samples
waveforms and capacitive touch buttons which can be used to completely demonstrate and evaluate the
DRV2603.
This document contains instructions for setup and operation of the DRV2603EVM-CT, as well as an in-
depth description and examples of haptic waveforms for LRA and ERM actuators.

1 Getting Started
The DRV2603 can be used as a demonstration or evaluation tool. When the DRV2603EVM-CT Evaluation
Module is powered on, a demo application automatically starts. To power the board, connect the
DRV2603EVM-CT to an available USB port on your computer using the included mini-USB cable. The
demo begins with a board power-up sequence and then will enter the demo effects mode. The four larger
buttons (B1-B4) can be used to sample haptic effects using both the ERM and LRA motor in the top right
corner. The two smaller mode buttons (“–“, “+”) are used to change between the different sets of effects.
See the DRV2603 Demonstration Program section for a more detailed description of the demo application.
