The DFRobot Gravity: Haptic Motor Driver for LRA Motors is a compact and easy-to-use module designed to generate precise and rich haptic feedback in electronic projects. Built around the TM6605 haptic driver chip, it allows developers to control Linear Resonant Actuator (LRA) motors through a simple I2C interface, making integration fast and hassle-free. The module supports a wide operating voltage range of 3.7V to 5.2V, ensuring compatibility with common development boards.
With 44 built-in vibration effects and automatic resonance tracking, the driver intelligently adapts to the connected LRA motor, delivering stable and optimized vibration performance without complex tuning. The Gravity connector further simplifies wiring, making it suitable for rapid prototyping and educational use. This haptic driver is ideal for adding tactile feedback to human-machine interfaces, interactive devices, and control systems where smooth and responsive vibration feedback is required.
