Bluetooth Haptic Kit

Texas Instruments recently introduced an innovative wireless haptic development kit. The DRV2605EVM-BT haptic Bluetooth kit comprises a 32-mm square PCB containing a DRV2605 haptic driver chip that controls an eccentric rotating mass motor (ERM) and a linear resonant actuator (LRA) to produce vibrations. The DRV2605 has an integrated library with more than 100 effects licensed from Immersion Corp.

You can use a circle of LEDs to display visual alerts. The board might be useful to speed up development times when designing and testing haptic effects in applications such as: watches, fitness trackers, wearables, portable medical equipment, touch screens, displays, and other devices requiring tactile feedback.

A SimpleLink Bluetooth low-energy CC2541 wireless microcontroller communicates with a free iOS app running on an iPhone or iPad. The app allows you to play predefined library waveforms, create new waveform sequences, and assign waveform sequences to in-app notifications. The app can also be used to quickly configure the DRV2605’s internal register settings: select between an ERM or LRA actuator, set the rated and overdrive voltages, configure and run autocalibration, send direct I2C commands, as well as set up the board to respond to a GPIO trigger.

The DRV2605EVM-BT haptic Bluetooth kit costs $99.
