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
