Adafruit LIS331 Wide-Range ±24g Triple-Axis Accelerometer - STEMMA QT/Qwiic

Overview

The Adafruit LIS331HH Triple-Axis High-G Accelerometer Breakout – STEMMA QT is designed for projects that experience extreme motion or impacts where typical accelerometers reach their limits. Powered by the ST LIS331HH sensor, it can measure acceleration ranges up to ±24g, making it ideal for robotics, crash detection, motion analysis, vibration monitoring, and other high-dynamics applications.

Unlike common accelerometers that max out around ±16g, the LIS331HH provides selectable ±6g, ±12g, and ±24g ranges, allowing you to capture high-impact events with reliable precision. The sensor also includes configurable high-pass and low-pass filters, helping you tune the readings for your specific application—whether filtering vibration noise or isolating sudden motion.

Communication is flexible thanks to both I2C and SPI interfaces, making it compatible with a wide variety of microcontrollers and development boards such as Arduino, Raspberry Pi, and Feather boards. The breakout board includes onboard voltage regulation and logic level shifting, allowing it to work safely with 3.3V and 5V systems.

Designed in the convenient STEMMA QT / Qwiic form factor, the board features plug-and-play JST connectors that enable quick solderless connections and easy sensor chaining. For advanced integrations, all pins are also broken out to standard 0.1" header pads, giving you full control over interrupts, chip select, and interface configuration.

With features like programmable interrupts, motion detection, free-fall detection, sleep-to-wake capability, and orientation detection, the LIS331HH breakout is a powerful solution for engineers and makers building systems that require accurate high-G motion sensing.
