# 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.
