KompassiIMU

KompassiIMU is an open-source inertial measurement unit (IMU) firmware and software suite designed primarily for microcontroller-based systems, particularly those using the STM32 microcontroller family. The project aims to provide robust and efficient algorithms for sensor fusion, enabling accurate estimation of orientation, angular velocity, and linear acceleration from data collected by onboard inertial sensors such as accelerometers, gyroscopes, and magnetometers.

Developed with modularity in mind, KompassiIMU supports various sensor configurations and allows users to customize sensor fusion algorithms. The firmware includes implementations of complementary filters, Kalman filters, and Madgwick/Mahony filters, which are commonly used for sensor fusion in embedded systems. The software is structured to facilitate integration with existing projects, offering flexibility for developers working on drones, robotics, wearable devices, or other applications requiring precise motion tracking.

The project is hosted on GitHub and follows an open-source license, encouraging community contributions and modifications. Users can access the source code, documentation, and example projects to adapt the firmware to their specific hardware and requirements. KompassiIMU is particularly well-suited for resource-constrained environments, as it is optimized for low computational overhead while maintaining high accuracy.

The name "Kompassi" derives from the Finnish word for "compass," reflecting the core functionality of orientation estimation. The project is maintained by a small team of developers and enthusiasts, with ongoing updates to improve performance, add new features, and address user feedback. It serves as a valuable resource for hobbyists, engineers, and researchers seeking a reliable and efficient solution for inertial navigation in embedded systems.
