MIKROE Vibro Motor 4 Click is a compact add-on board that makes an ideal solution for adding simple haptic feedback in any design. This board features the G1040003D, a coin-sized linear resonant actuator (LRA) that generates vibration/haptic feedback from Jinlong Machinery & Electronics, Inc. Driven by a flexible Haptic/Vibra driver, the DRV2605, G1040003D vibrates in the Z-axis, which is perpendicular to the face of the vibration motor. It draws a maximum of 170mA while producing the highest G force/vibration energy of 2 GRMS. This Click board™ makes an excellent choice for devices with limited battery capacity and for users who require crisp haptic feedback and low power consumption.

Vibro Motor 4 Click as its foundation uses the G1040003D, coin-sized linear resonant actuator that generates vibration/haptic feedback in the Z plane perpendicular to the motor's surface from Jinlong Machinery & Electronics, Inc. The G1040003D draws a typical 145mA while producing a G force of 2 GRMS and makes an excellent choice for applications requiring crisp haptic feedback and low power consumption. For haptic feedback applications, fast rise and fall times are critical for achieving the optimal user experience. That's why the rise time (50% power) of the G1040003D, which is 10ms, and its fall time (10% power) of 50ms makes it one of the best choices for haptic feedback applications.

Driven by the DRV2605, a flexible Haptic/Vibra driver from Texas Instruments, this Click board™ is designed to provide highly flexible haptic control over a standard I2C 2-Wire interface with a maximum clock frequency of 400kHz. It possesses enabling function, routed on the CS pin of the mikroBUS™ socket labeled as the EN, and comes up with an extensive integrated library of over 100 licensed effects that eliminates the need to design haptics waveforms. It also contains a smart-loop architecture and provides automatic overdrive and braking, creating a simplified input waveform paradigm, reliable motor control, and consistent motor performance.

Additionally, the DRV2605 can also operate in the PWM Mode and accept the PWM signal from the PWM pin of the mikroBUS™ socket. In this mode, the DRV2605 device drives the actuator continuously until the user sets the DRV2605 to a Standby Mode or enters another interface mode. More information about the operating modes of the DRV2605 can be found in the attached datasheet.

This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the I2C communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
