This is a mini vibration motor Grove module which is suitable as a non-audible indicator (as opposed to the very audible Grove Buzzer module). When the input is "HIGH", the motor will vibrate just like your cell phone on silent mode. The motor is easy to use and Grove compatible. Perfect for toys, cell phone modules or any other suitable project that requires a vibration motor.
