The Adafruit LIS331 Accelerometer Breakout features the LIS331HH from ST — a triple-axis accelerometer capable of measuring up to ±24g, well beyond the ±16g limit of most standard accelerometers. It's ideal for high-impact and high-vibration applications where typical sensors would clip.
Built in the STEMMA QT form factor, this breakout connects via solderless I2C cables compatible with SparkFun Qwiic. An onboard voltage regulator and level shifting let you use it with both 3.3 V and 5 V systems. All pins are also broken out to standard headers for breadboard use.
Key Features
- Wide Measurement Range – Selectable ±6g, ±12g, or ±24g on all three axes
- Configurable Filters – Built-in high-pass and low-pass filters to tune readings for your application
- Adjustable Data Rates – Configure measurement frequency to balance performance and power consumption
- Dual Interface – SPI and I2C connectivity for flexible integration
- STEMMA QT / Qwiic – Solderless I2C connectors on both sides for easy daisy-chaining
- 3.3 V and 5 V Compatible – Onboard voltage regulator and level shifting for Arduino Uno, Raspberry Pi, Feather, and more
- Arduino & CircuitPython Libraries – Ready-to-use libraries with example code
Ideal For
- High-impact and crash detection systems
- Vibration monitoring and analysis
- Robotics and motion-sensing projects requiring wide g-range
- Sports and activity tracking with high-acceleration events

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- 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.
- 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.
- STEMMA
- A plug-and-cable connection system used on some maker electronics boards to make wiring simpler. If a product uses STEMMA, you need the matching cable or connector type to plug it in without soldering.
- STEMMA QT
- A small plug-in connector system for I2C boards that lets you connect compatible sensors and controllers without soldering. It matters because it can make wiring faster and less error-prone, especially when adding several small modules to a project.
