Vibro Motor 2 Click is a compact add-on board that makes an ideal solution for adding simple haptic feedback in any design. This board features the VZ43FC1B5640007L, a compact Eccentric Rotating Mass (ERM) motor that generates vibration/haptic feedback from Vybronics, alongside a DMG3420U N-channel MOSFET to drive the ERM motor, since the MCU itself cannot provide enough power for the motor driving. It draws a maximum of 100mA while producing the highest G force/vibration energy of 0.91G. This Click board™ makes an excellent choice for many small handheld devices and for users who require crisp haptic feedback and low power consumption.

Vibro Motor 2 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

Vibro Motor 2 Click as its foundation uses the VZ43FC1B5640007L, a compact Eccentric Rotating Mass (ERM) motor that generates vibration/haptic feedback from Vybronics. This kind of motor contains a small eccentric weight on its rotor, so it also produces a vibration effect while rotating it. The VZ43FC1B5640007L draws a typical 100mA while creating a sizable vibration force of 0.91G and makes an excellent choice for applications requiring crisp haptic feedback and low power consumption. This Click board™ also uses the DMG3420U N-channel MOSFET to drive the ERM motor, since the MCU itself cannot provide enough power for the motor driving.

The gate of the MOSFET is driven by the PWM signal, routed to the PWM pin of the mikroBUS™ socket. The PWM signal toggles the MOSFET gate with pulses of a certain width. As a result, the current through the motor is varied depending on the pulse width of the PWM signal, which directly affects the speed of the motor, effectively controlling the vibration force that way. The circuit also contains a protection diode, which protects the transistor from the reverse voltage since the motor represents an inductive load. Turning off its current can produce a kickback voltage that can damage the transistor.

This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
