Description
Product Overview
The SparkFun Qwiic Haptic Driver DA7280 is a miniature linear resonant actuator (LRA) solution designed for developers who need precise, low‑power haptic feedback in their electronic projects. Integrated on a compact 1.18 × 1.06 × 0.24‑inch board, the driver pairs Dialog Semiconductor’s DA7280 motor driver IC with a built‑in LRA motor, delivering smooth, consistent vibrations. The board features two Qwiic connectors for plug‑and‑play I2C communication, eliminating the need for soldering, and includes optional 0.1‑inch‑spaced through‑hole pads for breadboard use. Key specifications include an ARM v7 processor, Bluetooth capability, a weight of just 0.317 oz, and a vibrant red color that makes it easy to locate on a prototype bench. Designed for the industrial and scientific market, it ranks highly in the Linear Motion Actuators category, reflecting its reliability and performance.

Usage
This driver excels in applications where tactile cues are essential, such as wearable devices, handheld controllers, robotics, and IoT gadgets. Whether you are building a custom game controller that needs a subtle click, a medical device that signals a user action, or an industrial sensor that alerts operators, the DA7280 provides a fast, repeatable vibration response. The Qwiic interface allows rapid integration with popular development platforms like Arduino, Raspberry Pi, and SparkFun’s own RedBoard, making it suitable for both hobbyists and professional engineers. Its low power consumption ensures long battery life in portable applications, and the optional PTH pads give you the flexibility to prototype on a breadboard before moving to a permanent PCB layout.

FAQ
Can I use the driver with a breadboard?
Yes. In addition to the Qwiic connectors, the board includes 0.1‑inch‑spaced through‑hole pads that expose I2C, power, interrupt, and GPIO pins, allowing you to place the module on a standard breadboard for rapid prototyping.
What voltage range does the driver operate at?
The DA7280 driver operates from 3.3 V to 5 V, making it compatible with most microcontroller platforms and ensuring safe operation in battery‑powered applications.
Is the vibration motor replaceable?
The built‑in LRA motor is soldered onto the board for a compact form factor. If you need a different motor type or strength, you can design a custom carrier board that uses the same DA7280 driver IC, but the supplied module is intended as a complete, ready‑to‑use solution.
How do I program custom vibration patterns?
Using SparkFun’s open‑source libraries, you can send I2C commands to set vibration amplitude, duration, and repeat intervals. The driver also supports PWM input, allowing you to generate custom waveforms directly from a microcontroller.
What is the typical response time of the actuator?
The LRA motor responds within a few milliseconds, providing near‑instantaneous tactile feedback that feels natural to users in interactive applications.
