Features: Premium: Using quality 1027 mobile phone vibration motor, the vibration effect is-obvious. MOS-amplification drive, can be directly controlled by the digital port, can control the vibration strength of the motor through PWM. This module can easily convert electrical signals to mechanical vibration. This small built-in module uses a quality vibration motor. You can make some interesting projects such as an alarm, a notifiers or even a vibrating robot! When the input is high, the motor will vibrate just like your cell phone. The vibration motor module is suitable for making vibration-sensitive interactive products, portable vibration reminders for intelligent devices, etc. Notice: 1.Actual color may be slightly different from the image due to different light effect 2.Please allow 1-3cm deviation due to manual measurement Description: Item Type:Vibration Module Rated Voltage: 5.0VDC Working Voltage: DC 3.0 - 5.3V Rated Speed: 9000RPM Rated Current: 60mA Starting Current: 90mA Starting Voltage: DC 3.7V Package List: 3pcs Vibration Motor Module
