DRI0056

DRI0056 is a Gravity: haptic motor driver for LRA motors. This is a compact controller module designed for Linear Resonant Actuators (LRAs), enabling high‑fidelity tactile feedback in embedded electronics and interactive systems. Powered by the TM6605 haptic driver chip, this tactile control board converts simple I2C commands into rich vibration effects suitable for robotics, gaming interfaces, and smart user interfaces. Operating from 3.7V–5.2V and supporting LRA frequencies between 140–220Hz, the haptic feedback module combines automatic resonance tracking, a large built‑in vibration library, and a plug‑and‑play Gravity interface for seamless integration with controllers such as Arduino and Raspberry Pi.
