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.

    MSP430 Pin-Out 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.
