DRV2604 ERM, LRA Haptic Driver Evaluation Kit
The DRV2604 is a haptic driver designed for Linear Resonant Actuators (LRA) and Eccentric Rotating
Mass (ERM) motors. It provides many features which help eliminate the design complexities of haptic
motor control including reduced solution size, high efficiency output drive, closed-loop motor control, quick
device startup, memory for waveform storage, and auto-resonance frequency tracking.
The DRV2604EVM-CT Evaluation Module (EVM) is a complete demo and evaluation platform for the
DRV2604. The kit includes a microcontroller, linear actuator, eccentric rotating mass motor, and capacitive
touch buttons which can be used to completely demonstrate and evaluate the DRV2604.
This document contains instructions to setup and operate the DRV2604EVM-CT in demo and evaluation
mode.

Page 4: Getting Started
Getting Started The DRV2604 can be used as a demonstration or evaluation tool. When the DRV2604EVM-CT evaluation module is powered on for the first time, a demo application automatically starts. To power the board, connect the DRV2604EVM-CT to an available USB port on your computer using the included mini-USB cable. -
Page 5: Evaluation Module Operating Parameters
Select USB (5 V) or VBAT power for the DRV2604 2. Connect the included mini-USB cable to the USB connector on the DRV2604EVM-CT board. 3. Connect the other end of the USB cable to an available USB port on a computer, USB charger, or USB battery pack. -

Page 11: Additional Hardware Modes
Additional Hardware Modes Additional modes are available on the DRV2604EVM-CT providing increased board control and functionality. The additional modes are not available in demo mode, but can be accessed by switching to binary counting mode. In binary counting mode the mode LEDs count in binary (32 modes) rather than in demo mode format (only 6 modes including off). -
