High compatibility: The module is equipped with STEMMA QT/Qwiic interface, supports plug-and-play, no soldering required, and can be directly connected to for , for , for , for (for Qwiic compatible devices), ensuring seamless integration and operation. Universal voltage range: It can work efficiently within the 2-5V DC voltage range, suitable for a variety of electronic applications. Advanced tactile feedback: Adopts DRV2605L driver to provide precise tactile feedback and enhance user interaction experience. Compact design: The module is compact and , making it an ideal choice for DIY electronics and robotics projects. Vibration feedback: The motor drive controller designed for tactile feedback (Haptic) adopts I²C interface, built-in LRA (Linear Resonant Actuator) and ERM (Eccentric Rotor Motor) drive algorithm, which can provide rich and real-time vibration feedback. Multiple motors supported: LRA (Linear Resonant Actuator): Precisely control vibration frequency; ERM (Eccentric Rotor Motor): Traditional vibration motor driver Efficient drive: Output current up to 800mA (can drive high-power motors); Working voltage 2V-5.2V (compatible with 3V/5V system) Core features: Built-in effect library: Pre-stored 123 tactile effects (click, vibration, pulse, etc.) Support real-time PWM input custom vibration mode Intelligent control: Automatic resonance tracking (Auto-Calibration): Optimize LRA performance Low power mode: Standby current is only 1μA Plug and play interface: STEMMA QT/Qwiic (I²C interface, default address 0x5A) Technical parameters: Working voltage 2V - 5.2V (recommended 3.3V or 5V) Maximum output current 800mA (instantaneous) Control interface I²C (Qwiic), PWM input Built-in effect library 123 preset effects Motor type support LRA, ERM Interface description (STEMMA QT/Qwiic) Pin Function Color (Qwiic line sequence) GND Ground Black VIN Power input (2V-5.2V) Red SDA I²C data line Blue SCL I²C clock line Yellow Note: M+ / M- Connect to the motor (external terminals of some modules). pin (interrupt output, optional).
