Mikroe Vibro Motor Click Board™

Mikroe Vibro Motor Click Board™ is designed to add one-pin-driven haptic feedback on small handheld devices. This Mikroe click board features an Eccentric Rotating Mass (ERM) motor that contains a small eccentric weight on its rotor which produces a vibration effect. The Vibro Motor click board offers low power consumption and is constructed in a compact size. This board uses the DMG3420U and small MOSFET to drive the ERM motor and the protection diode protects the transistor from reverse voltage. The PWM signal toggles the gate of the MOSFET that controls the current through the motor which directly affects the speed of the motor. The Vibro Motor click board is ideal for application in pagers, RFID scanners, and cell phones.
