The Adafruit ISM330DHCX is an industrial-quality 6-DoF IMU from ST, combining a 3-axis accelerometer and 3-axis gyroscope on a single silicon die for synchronised measurements. With an extended gyroscope range of ±4000°/s and an industrial temperature range of −40°C to +105°C, it delivers exceptional performance where standard IMUs fall short.
Built-in smart features include tap detection, activity recognition, a pedometer/step counter, and a programmable finite state machine with machine learning core for basic gesture recognition. The breakout board includes voltage regulation and level shifting for 3.3V or 5V compatibility, plus STEMMA QT / Qwiic connectors for solderless I2C wiring.
Key Features
- Accelerometer – ±2/±4/±8/±16 g range at 1.6 Hz to 6.7 kHz update rate
- Gyroscope – ±125/±250/±500/±1000/±2000/±4000°/s at 12.5 Hz to 6.7 kHz
- Industrial Temperature Range – −40°C to +105°C with calibration for stable accuracy
- Single-Die Design – Accelerometer and gyroscope synchronised on the same silicon
- Smart Features – Tap detection, activity detection, pedometer, finite state machine, ML core
- I2C & SPI Interface – Two configurable interrupt pins; external I2C/SPI port for OIS
- STEMMA QT / Qwiic Connectors – Solderless I2C connection with daisy-chain support
- 3.3V & 5V Compatible – Onboard voltage regulation and level shifting

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.
- Gyroscope
- A gyroscope measures rotation, such as how fast a board is turning around its X, Y, and Z axes. This matters for projects like gesture controls, balancing robots, and motion tracking where tilt or rotation changes need to be detected.
- 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.
- IMU
- An IMU (Inertial Measurement Unit) combines motion sensors, typically an accelerometer and gyroscope and sometimes a magnetometer, to measure movement and orientation. It can sense motion, tilt, vibration, rotation, and changes in direction, which is useful for tasks such as navigation, stabilisation, gesture detection, and asset tracking.
- 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.
