Adafruit DRV2605L Shield

Overview

The Adafruit DRV2605L Haptic Motor Controller Shield features a TI DRV2605 Haptic Driver and two STEMMA QT connectors. Note that DRV2605L is a low-voltage version of DRV2605.

Requirements

This shield can be used with boards which provide an I2C connector, for example STEMMA QT or Qwiic connectors. The target board must define a zephyr_i2c node label. See Shields for more details.

Pin Assignments

Shield Pin	Function
SDA	DRV2605 I2C SDA
SCL	DRV2605 I2C SCL
IN/TRIG	Digital input for triggering haptic effects

The haptic motor could be of type eccentric rotating mass (ERM) or linear resonant actuator (LRA). By default an ERM motor is specified in the devicetree file for this shield, as this is the type of motor that Adafruit sells with this shield. Modify the devicetree file if you use an LRA motor; see ti,drv2605 for details.

Programming

Set --shield adafruit_drv2605l when you invoke west build. For example when running the DRV2605 Haptic Driver haptics sample:

# From the root of the zephyr repository
west build -b adafruit_qt_py_rp2040 --shield adafruit_drv2605l samples/drivers/haptics/drv2605
