Update

R2.0 is available and has the pin layout reversed from R1.0 to be the same as other Flex Module layouts.

What is it?

(This is a replacement for the early DRV2605L Flex Module. We updated the VDD and GND inputs, so that they are reversed and compatible with all other Flex Modules.)

A Flex Module is a tiny breakout board that is both breadboard-able and designed to solder/epoxy to flexible PCB for wearable prototyping. The LRA Haptic Flex Module is based on the DRV2605L Haptic Driver. The design is tiny to fit on the opposite side of a flexible circuit board from the ERM/LRA vibrator with a neoprene pad dampener. The allows for maximum flexibility of the circuit. It could also be attached directly to the motor, though durability would be limited.

Why did you make it?

This Flex Module will drive both linear resonant actuators (LRAs) and eccentric rotating mass (ERM) motors for haptic vibration. With an LRA, there is over 100 unique effects that can be selected from the internal licensed haptic IP.

What makes it special?

This design includes both PWM and audio line input option to drive the motor directly. So audio can be outputted over the motor driven or a microcontroller can drive the LRA by PWM directly.

We carry a selection of compatible motors

• Samsung LRA haptics - recommended
• Precision Microdrives C10-100
• ERM based vibrators

PIEZO != LRA If you want to drive our Piezo Actuators, use the Piezo Haptic Flex Module. (It is amazing that this must be said.)

The DRV2605L has a single i2c address and drives a single motor. To control multiple LRA Haptic Flex Modules on the same i2c bus, please utilize the i2c Switch Flex Module.

Software available:

• Adafruit Arduino compatible
• Precision Microdrives Arduino compatible

Designed, fabricated, and shipped from the US.
