Mini Coin Vibration Motor – 3V DC, 10mm Diameter
Mini Coin Vibration Motor – 3V DC, 10mm Diameter
The coin vibration motor is a compact DC motor with an eccentric rotating mass, producing vibrations that can be felt but not heard. It is commonly used in wearable devices, mobile phones, and DIY haptic feedback systems. Its small size and low power consumption make it ideal for embedded electronics projects.

Compatibility
This motor operates at 3V and draws up to 100mA, making it compatible with 3.3V boards like ESP32 and Raspberry Pi Pico, as well as 5V Arduino boards with a current-limiting resistor or transistor driver. Pair it with an NPN transistor (e.g., 2N2222) and flyback diode for safe GPIO control.
Wiring Notes
Connect red wire to positive supply (3V) and black to ground. To control from a microcontroller pin, use a transistor to handle the motor current, as most GPIO pins cannot source more than 20-40mA. Always add a flyback diode across the motor terminals to protect against voltage spikes.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, but you must use a transistor or motor driver circuit since the Arduino pin cannot supply enough current. Connect the base of an NPN transistor through a resistor to the pin, and run the motor from the 5V supply.
Can I power it directly from a 3.7V LiPo battery?
Yes, the motor can handle up to 4V intermittently. For continuous use, a small series resistor or PWM duty cycle reduction is recommended to stay near the rated 3V.
How strong is the vibration?
At 3V, the vibration is noticeable but mild—similar to a smartphone on silent. It is suitable for subtle haptic alerts, not for massaging applications.
