Product Description

Now available from Tronixlabs Australia is this convenient DRV2605 breakout board from adafruit. The DRV2605 from Texas Instruments is a very clever little motor driver - which is designed specifically for controlling haptic motors - buzzers and vibration motors, rather than controlling a stepper motor or DC motor.

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.

The DRV2605 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 built in effects are much much nicer than just 'on' and 'off' and will make your haptic project way nicer feeling. According to the product page, it can be used with both LRA (Linear Resonance Actuator) and ERM (Eccentric Rotating Mass) type motors but we have only used it with our little vibration pancake ERM.

The DRV2605 breakout works with both 3V and 5V power/logic, and we have code specifically for Arduino but porting it to any I2C-capable processor should be quite simple. Check it out and get buzzing!
