Gravity: I2C Haptic Motor Driver for LRA Motors (TM6605, 44 Modes)

The Gravity I2C Haptic Motor Driver is a dedicated controller board designed for Linear Resonant Actuator (LRA) motors. Powered by the TM6605 driver chip, it allows makers, students, and developers to easily integrate precise tactile feedback into their interactive electronics projects.

Dedicated TM6605 haptic chip

The board features a specialised TM6605 IC tailored for driving LRA motors with consistent output. It manages motor drive signals directly to produce clean, controlled haptic sensations.

44 built-in vibration modes

The driver includes 44 pre-programmed vibration modes for varied tactile effects. This allows you to deploy diverse haptic cues quickly without needing to manually generate waveform sequences in your code.

Automatic resonance tracking

Equipped with automatic resonance tracking from 140Hz to 220Hz, the driver dynamically adjusts to the actuator's optimal frequency. This ensures peak vibration strength and efficient power delivery during operation.

Standard I2C communication

The module uses an I2C interface to communicate with your microcontroller, requiring minimal wiring. This simplifies connection and conserves I/O pins for other project components.
