The DRV2605EVM-BT is an evaluation kit for the DRV2605 ERM and LRA Haptic Driver. The kit connects
the DRV2605 to an iOS App. wirelessly over Bluetooth Low Energy to allow control, creation, and
customization of haptic effects. Use the included app to demonstrate the use of haptics in smart watches,
fitness trackers, wearable devices, or to "haptify" any application without having to connect wires
externally to a micro-controller. The app. includes notification demos, waveform playback, and DRV2605
register control.
The DRV2605 contains an embedded waveform library licensed from Immersion that supports driving
eccentric rotating mass motors (ERM) or linear resonant actuators (LRA). With the included LRA, mount it
and immediately begin using the DRV2605 library through the iOS App. The DRV2605EVM-BT can also
be powered either by a 5V USB power supply using the included micro-USB cable or by 3xAAA batteries
using the included battery pack with JST connector.

The DRV2605EVM-BT will appear on the iOS device color coded based on the RSSI strength. If the board was previously connected to the iOS device, a "Previously Connected" tag will appear. This helps to identify a particular board when multiple boards are advertising simultaneously. -
Page 5: Hardware Overview
The DRV2605 is configured to play LRA actuator waveforms on statup which can be configured differently if needed. The DRV2605EVM-BT has optional pad to set into an external trigger mode to play a particular pattern on an external microcontroller output trigger. An example of this is described in Section 5.11. - Page 6 DC-DC converter is operational. The board is configured in PFM mode through a resistor R37 which pulls the PFM/PWM pin to low. The REGVDD is the fixed 3.3-V rail for the board. DRV2605EVM-BT User's Guide SLOU391 – May 2014 Submit Documentation Feedback Copyright © 2014, Texas Instruments Incorporated...
