Product description: Qwiic haptic controller - DA7280 - SparkFun ROB-17590
A haptic/touch controller manufactured by Sparkfun. The module features a small Linear Resonant Actuator (LRA) vibration motor and Dialog Semiconductor's DA7280 motor driver chip for touch feedback applications. The module communicates via I2C, PWM or three general purpose input pins. The board features a Qwiic connector and pinouts in the form of goldpin solder holes. The solder hole pattern is 2.54 mm, which is a standard pin layout used e.g. in contact boards for rapid prototyping of circuits. The module will be useful in connection with the robot, it will inform when the robot hits the wall.

On the board was soldered vibration motor LRA, which can also be placed outside the board, by soldering wires in its place. The module is equipped with two Qwiic connectors, which can be used to easily connect it to the main module and to connect another I2C module with Qwiic connector. I2C address of DA7280 chip is 0x4A. The board works with 3.3V voltage, manufacturer recommends to power module via Qwiic connector, however there are also pinouts available for soldering 2.54mm goldpin strip.
SparkFun Qwiic connection system
SparkFun Q wiic ecosystem of simple and fast connection of sensors, actuators, overlays and I2C wires is low error prone. Modules equipped with the Qwiic connector feature a 4-pin JST connector with a 1 mm raster. Thanks to this solution, the connector does not take up much space on the board and makes it impossible to connect the plug in the reverse way, minimizing the risk of error when connecting the wires.
The module is equipped with two Qwiic connectors.
Board with vibration motor.
