DFRobot Gravity LRA Haptic Motor Driver Module
DFRobot Gravity LRA Haptic Motor Driver Module features a Gravity I2C interface, 44 built-in vibration effects, and auto resonance tracking. This module for Linear Resonant Actuator (LRA) motors is based on the TM6605 chip and operates on a versatile 3.7V to 5.2V supply range. The Gravity LRA haptic motor driver module supports LRA frequencies ranging from 140Hz to 220Hz. This module offers auto-calibration, ensuring the motor consistently delivers the maximum vibration strength and the crisp feedback possible, without requiring complex manual tuning or calibration procedures. The Gravity LRA haptic motor driver module uses the standard Gravity I2C interface for seamless connection to various microcontrollers, including Arduino, Raspberry Pi, and UNIHIKER. This module is ideal for rapid integration into robotics, interactive controllers, and smart user interfaces.
The module comes pre-loaded with 44 distinct, pre-programmed vibration patterns. This module provides an extensive library that allows immediate implementation of complex tactile effects ranging from subtle clicks to strong rumbles, directly via simple I2C commands. The module with this feature significantly accelerates development and eliminates the need for manual waveform programming, allowing creators to focus on the user experience.
