Vibro Motor 3 Click is a compact add-on board that makes an ideal solution for adding simple haptic feedback in any design. This board features the G0832022D, a coin-sized linear resonant actuator (LRA) that generates vibration/haptic feedback in the Z plane, perpendicular to the motor's surface from Jinlong Machinery & Electronics, Inc. Driven by a flexible Haptic/Vibra driver the DRV2605, the G0832022D vibrates in the Z-axis, which is perpendicular to the face of the vibration motor. It draws only 19mA at 0.6V while producing a G force of 0.55 GRMS, making it ideal for battery-powered wearables. This Click board™ makes an excellent choice for devices with limited battery capacity and for users where crisp haptic feedback and low power consumption are required.
Vibro Motor 3 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.
Vibro Motor 3 Click is based on the G0832022D, a 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 G0832022D draws only 19mA at 0.6V while producing a G force of 0.55 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.
Driven by the DRV2605, a flexible Haptic/Vibra driver from Texas Instruments, this Click board™ is designed to provide extremely-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, which allows effortless auto resonant drive for LRA motor drive. This feedback provides automatic overdrive and braking, which creates a simplified input waveform paradigm as well as 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. In PWM Mode, the strength of vibration is controlled by the duty cycle, and for the LRA motor, the DRV2605 automatically tracks the resonance frequency unless the LRA_OPEN_LOOP bit in register 0x1D is set. If the LRA_OPEN_LOOP bit is set, then the LRA motor is driven according to the frequency of the PWM input signal. More information about the operating modes of the DRV2605 can be found in the attached datasheet.
This Click board™ is designed to operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. It allows for both 3.3V and 5V capable MCUs to use the I2C communication lines properly. However, the Click board™ comes equipped with a library that contains easy to use functions and an example code which can be used, as a reference, for further development.
