Boardoza Vibration Motor Driver Breakout Board
Overview
The Boardoza Vibration Motor Driver is a specialized, compact breakout board designed for precision control of DC vibration motors (ERM) and Linear Resonant Actuators (LRA). Engineered for haptic feedback applications, this module provides a seamless interface between low-power microcontrollers (such as ESP32, STM32, or Arduino) and high-current vibration motors.
With its 25x25mm ultra-compact footprint, it is an ideal solution for wearable devices, handheld controllers, and industrial alert systems where tactile notification is required.

Key Engineering Features
Precise Haptic Control
Unlike direct GPIO driving, which can damage microcontroller pins due to back-EMF (Electromotive Force), this breakout board features integrated flyback protection. This ensures the safety of your MCU while allowing for high-frequency PWM switching to create complex haptic patterns (e.g., varying pulse strengths, ramps, and patterns).
Low Power Consumption
Designed with mobile and battery-operated applications in mind, the driver minimizes quiescent current draw, ensuring that the vibration system does not significantly impact the overall power budget of the device during idle states.
Modular Integration
The standardized pinout allows for rapid integration into existing prototyping ecosystems. The board serves as a robust power stage, translating low-current logic signals into the high-current drive required by eccentric rotating mass (ERM) motors.
Applications
Wearable Haptics: Silent alerts for smartwatches and fitness trackers.
User Interface Feedback: Tactile confirmation for touchless buttons or industrial panels.
Alert Systems: Non-visual notification systems for noisy industrial environments.
Medical Devices: Discrete vibration prompts for patient monitoring equipment.
