Product details

This miniature vibration motor (ERM) provides reliable vibration for a variety of electronic applications. Its small size and low supply voltage make it suitable for haptic feedback in wearable devices, compact alarms, notification systems and DIY projects. Wires are attached for easy connection.

 

⚠ Important notice for ESP32: This vibration motor draws up to 70 mA during normal operation and up to 90 mA at startup. This significantly exceeds the current capability of the ESP32 GPIO pins (the recommended current per GPIO is at most 12 mA, and the absolute maximum is approximately 40 mA, with a risk of damaging the chip). The motor must therefore be controlled through a transistor, MOSFET or suitable driver, and you must never connect it directly to an ESP32 output pin.
