Add motion sensing to your project with this Qwiic-enabled LIS3DH breakout. The LIS3DH is a smart, low-power, three-axis capacitive micro-machined accelerometer with 12-bit resolution, suited to translation, motion, orientation and tap detection.
This board is classified as a 3DoF, or 3 Degrees of Freedom, sensor. It uses the STMicroelectronics LIS3DH and includes a pair of Qwiic connectors on a standard 1in. by 1in. breakout, making it easy to drop into the SparkFun Qwiic ecosystem.
You can connect it over SPI or I2C, then provide 3.3V and ground. It also works nicely with a breadboard for easy prototyping, and SparkFun provides supporting documentation including a schematic, KiCad files, hookup guide, LIS3DH datasheet, app note, Arduino library and hardware repository.
The LIS3DH Breakout is a 3.3V device. Supplying voltages greater than ~3.6V can permanently damage the IC. If you use I2C with an Arduino that has a 3.3V supply output, extra level shifting should not be required; SPI use may need a level shifter.

Jargon buster
Plain-language definitions for the technical terms used above.
- 12-bit resolution
- 12-bit resolution means the sensor’s measurement is divided into 4096 possible digital values. Higher resolution can make small changes in motion or tilt easier to detect, as long as the sensor range and noise are suitable for the project.
- 3DoF
- 3DoF means “three degrees of freedom,” usually measuring motion along three axes: X, Y and Z. For this accelerometer, it tells you the board can sense acceleration and tilt in three directions, but not rotation like a gyro would.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- FIFO
- FIFO stands for “first in, first out” and is a small memory buffer inside the sensor that stores recent readings in order. This matters because it can help capture motion data without the microcontroller needing to read the sensor every single instant.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- LIS3DH
- A specific low-power 3-axis accelerometer chip made by STMicroelectronics. Knowing the chip part number helps you find the correct datasheet, libraries, wiring details, and limits such as its safe voltage range.
- Motion detection
- A camera feature that checks the image for changes that suggest something has moved. It matters because your project can use movement as a trigger instead of constantly saving or processing every frame.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
