The Adafruit DRV2605L Haptic Motor Controller is a dedicated driver for haptic feedback motors, controlled via I2C. Rather than simple on/off control, the TI DRV2605L chip offers a library of over 100 built-in vibration effects — clicks, ramps, buzzes, and patterns — that create far more refined tactile feedback for your projects.
Multiple effects can be queued in the chip's internal memory and triggered in sequence. The controller supports both LRA (Linear Resonance Actuator) and ERM (Eccentric Rotating Mass) motor types, and works with 3V and 5V power/logic levels. Compatible with CircuitPython and Arduino libraries.
Key Features
- 100+ Built-In Effects – Clicks, ramps, buzzes, pulses, and complex vibration patterns
- I2C Control – Simple two-wire interface for triggering effects
- Effect Sequencing – Queue multiple effects in chip memory for automated playback
- Audio-to-Vibration Mode – Drive haptic output from an audio/music input
- LRA and ERM Support – Works with both linear and eccentric rotating mass motors
- 3V and 5V Compatible – Works with a wide range of microcontrollers
Ideal For
- Haptic feedback in wearables and controllers
- Tactile UI indicators and notifications
- Interactive art installations
- Accessibility devices with vibration feedback

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- vibration motor
- A small motor with an off-centre weight on its shaft, which shakes when it spins. It matters when choosing haptic feedback, alerts, or simple movement effects, as you need to match its voltage, current draw, size, and mounting style to your project.
