This Wireling lets you control a Linear Resonant Actuator (LRA) motor via the I²C bus and the DRV2605 IC. The DRV2605 Haptic Driver chip includes a licensed library of over 100 pre-programmed waveforms that generate a variety of effects.

Use this Wireling to create haptic motor vibration effects. Due to the 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. 

LRA motor pictured is pre-soldered to the circuit board and includes a sticky adhesive that can be used to attach the motor to the back of the board or another surface.

Note* 5-Pin Wireling cables not included and sold separately.
