Haptic Motor Driver - DRV2605L - SparkFun ROB-14538

Product description: DRV2605L - I2C haptic motor driver - SparkFun ROB-14538

SparkFun module with DRV2605L haptic motor controller. It can handle ERM (Eccentric Rotating Mass) and LRA (Linear Resonance Actuator) motors. It operates from 2 V to 5.2 V. It communicates via the I2C bus.

Manufacturer prepared user manual and library for Arduino.

The default firmware for DRV2605L is set to work with ERM motors. The manufacturer's library shows six different ERM effects and one LRA effect.

Features of the haptic motor controller

• Flexible haptic and vibration controller for ERM and LRA motors
• Digital motor playback control via I2C
• Audio to vibration conversion
• PWM input with 0 % to 100 % control range
• Hardware trigger input
• Built-in waveform sequencer and trigger
