Unit Vibrator is a high-performance vibration feedback module based on an N20 motor and a metal eccentric wheel. It generates physical vibration through the high-speed rotation of the eccentric wheel, enabling precise haptic feedback functionality. This unit communicates via a Grove HY2.0-4P interface and supports GPIO digital control as well as PWM pulse-width modulation. The vibration intensity can be steplessly adjusted by changing the PWM duty cycle. The module integrates an N-Channel MOSFET low-side switch driving circuit, features a motor speed of 8800 RPM, and recommends a PWM frequency of 10KHz. It also adopts a LEGO-compatible hole design, allowing flexible integration into various structures. It is suitable for applications requiring tactile feedback, such as electronic product notifications, touch feedback systems, and user interaction feedback.
