LRA Driver Whisker


Whisker Kickstarter Item

Note: This item is currently only available on Kickstarter, it will be for sale on our site after the Kickstarter is complete and rewards have been fullfilled


This Whisker lets you control a Linear Resonant Actuator (LRA) via the I²C bus and the DRV2605 IC, to create Haptic vibration type motion. Due to their construction and operating method, LRAs outlast traditional vibration motors several times over and are tuned to operate at frequencies that are optimal for skin contact. 

This Haptic Driver also includes a licensed library of pre-programmed waveforms which generate a variety of effects, activated by I²C commands. 

The Whisker Adapter TinyShield (ASD2022) incorporates level shifting and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V.
