Overview
Bring tactile feedback back to your hardware design with the Haptic Click Board™, featuring the DRV2605 IC, a driver for ERM (Eccentric Rotating Mass) and LRA (Linear Resonant Actuator) vibration motors. The DRV2605 module incorporates an extensive library with over 100 licensed haptic effects. These consist of an audio-to-vibe feature, where the motor vibrates in tune with the lower frequency range of audio input. A 3.5mm audio jack is also integrated into the board to use this functionality. The board also has screw terminals for secure connection to the ERM and LRA motors.
The Haptic Click Board™ communicates with the target microcontroller using the MikroBUS I2C (SCL, SDA), EN (in place of CS) and PWM pins. It uses a 3.3V or 5V power supply.
IC/Module: DRV2605 Haptic Driver
DRV2605 is an extremely-flexible haptic driver for LRA and ERM motors over a shared I2C compatible bus. It relieves the host processor from pulse-width modulated (PWM) drive signals, saving both costly timer interrupts and hardware pins. With an extensive integrated library over 100 licensed effects, it offers a licensed version of the TouchSense 2200 software from Immersion. It features a real-time playback mode via I2C.

Smart-Loop Architecture
With smart-loop architecture, Haptic Click Board™ allows effortless auto resonant drive for LRD and feedback-optimized ERM drive. This feedback provides automatic overdrive and braking, which creates a simplified input paradigm as well as dependable motor control and steady motor performance.
SMD Jumpers
Haptic Click Board™ can be used either with a 3.3V or 5V power supply. A zero-ohm SMD jumper allows user to switch between the two. Another pair of jumpers (R4 and R5) is designed to enable the user to choose from the left and right audio channels. It is soldered to R5 for right channel, by default. The PWM trigger will be disabled in case the PWM SEL jumper is unsoldered.
