The DRV2605 from TI is a fancy little motor driver. Rather than controlling a stepper motor or DC motor its designed specifically for controlling haptic motors buzzers and vibration motors. Normally one would just turn those kinds of motors on and off but this driver has the ability to have various effects when driving a vibe motor. For example ramping the vibration level up and down ‘click’ effects different buzzer levels or even having the vibration follow a musical/audio input.

This chip is controlled over I2C after initialization a ‘string’ of multiple effects can be strung together in the chips’ memory and then triggered to actuate in a row. The builtin effects are much much nicer than just ‘on’ and ‘off’ and will make your haptic project a way nicer feeling.

It can be used with both LRA (Linear Resonance Actuator) and ERM (Eccentric Rotating Mass) type motors.

This chip is 35V compliant making it a perfect choice for interfacing with any 3V or 5V microcontroller or computer such as Arduino or Raspberry Pi.

As if that weren’t enough SparkFun qwiic compatible STEMMA QT connectors are also added for the I2C bus so that soldering is not required. For a nosolder experience just wire up to your favorite micro using a STEMMA QT adapter cable. The Stemma QT connectors also mean the breakout can be used with various associated accessories. QT Cable is not included.
