The Adafruit H3LIS331 is an ultra-high-range triple-axis accelerometer capable of measuring up to ±400g across all three axes. Part of the ST LIS331 family, it's designed for applications where standard ±16g accelerometers aren't enough — from high-impact testing and industrial machinery monitoring to rocket and high-speed vehicle projects.
The breakout board comes in the STEMMA QT form factor with Qwiic-compatible I²C connectors on both sides for solderless daisy-chaining. All pins are also broken out to standard headers, and on-board voltage regulation and level shifting support both 3.3V and 5V systems. The sensor communicates over I²C or SPI.
Key Features
- ±400g Measurement Range – Ultra-high range across three axes for extreme acceleration sensing
- Configurable High-Pass and Low-Pass Filters – Built-in filters to tailor readings to your application
- Adjustable Data Rates – Control measurement frequency to match your power budget
- I²C and SPI Interfaces – Flexible connectivity options
- STEMMA QT / Qwiic Connectors – Solderless I²C connection, compatible with SparkFun Qwiic ecosystem
- 3.3V and 5V Compatible – On-board voltage regulator and level shifting
- Arduino and CircuitPython Libraries – Ready-to-use driver support with example code
Ideal For
- High-impact and shock measurement applications
- Rocketry and high-speed vehicle telemetry
- Industrial vibration and machinery monitoring
- Sports science and crash testing instrumentation

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny 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 connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- 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.
- 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.
