7Semi BMI330 6-DoF IMU Module - 6-Axis Accelerometer and Gyroscope with I2C Interface for Robotics, Navigation, and Motion Sensing
The 7Semi BMI330 IMU Module is a compact motion-sensing breakout board built on Bosch's BMI330 inertial measurement unit. It integrates a 16-bit 3-axis accelerometer and a 16-bit 3-axis gyroscope on a single board, delivering accurate orientation, rotation, and vibration data for a wide range of embedded applications. The module operates at 3.3 V and supports a Qwiic-compatible I2C interface for plug-and-play connectivity, for systems that require higher-speed communication. Its on-chip motion-triggered interrupt capability and built-in power management unit make it well-suited for low-power designs where reliable motion detection is critical.
With an operating range of -40 degrees C to +105 degrees C and configurable measurement ranges on both axes, the BMI330 module is designed for use in industrial monitoring, robotics, wearable devices, and IoT systems. The compact 24 x 15 x 4.8 mm footprint ensures easy integration into space-constrained designs, while its 16-bit digital output on all 6 axes provides the resolution required for precision navigation and predictive maintenance applications.
