DFRobot Fermion: BMI323+BMM350 9DOF IMU Sensor (I2C, Breakout)

DFRobot Fermion: BMI323+BMM350 9DOF IMU Sensor (I2C, Breakout) is a compact, high-precision inertial measurement unit designed for advanced motion sensing and orientation detection. It combines the Bosch BMI323 6-axis IMU with the Bosch BMM350 3-axis magnetometer to provide accurate 9-axis motion tracking. Featuring built-in hardware motion algorithms, the module supports step counting, tap detection, tilt sensing, free-fall recognition, and activity classification without increasing the host controller workload. Its low-noise architecture, on-chip temperature compensation, and integrated 2048-byte FIFO buffer ensure stable and reliable data output. With configurable operating modes and ultra-low power consumption, it is ideal for battery-powered devices. The I²C interface enables seamless integration with Arduino, Raspberry Pi, ESP32, and other embedded platforms for robotics, navigation, wearable devices, and motion control applications.
