The x-IMU was designed to be the most versatile Inertial Measurement Unit (IMU) and Attitude Heading Reference System (AHRS) platform available. Its host of on-board sensors, algorithms, configurable auxiliary port and real-time communication via USB, Bluetooth or UART make it both a powerful sensor and controller. The on-board microSD card , battery charger (via USB), real-time clock/calendar and motion trigger wake up also make the x-IMU an ideal standalone data logger.

Retired Product

The x-IMU is a retired product and is no longer available to purchase. The recommended replacement is the x-IMU3.

Stream by USB, Serial, or Bluetooth

Measurements can be streamed in real-time through multiple interfaces. USB provides a convenient wired connection for most operating systems. A configurable serial interface offers additional compatibility with embedded and industrial systems. Bluetooth connectivity provides further cross-platform support for wireless desktop and mobile applications.

Self-Contained Data Logger

In addition to its real-time streaming capabilities, the x-IMU can function as a stand-alone data logger. The on-board microSD supports up to 32 GB for hundreds of hours of storage. A battery life of up to 18 hours and motion trigger wake up allow the x-IMU to be deployed for multiple days. Files can be converted to CSV for use with applications such as Excel, MATLAB, and Python.

Open Source Software

The x-IMU software is free and open-source. The Windows GUI can be used to view real-time measurements as graphs or a 3D visualisation, and log streamed data to CSV for use with applications such as Excel, MATLAB, and Python. User software development and integration is supported by an open source C# API.
