DFRobot Gravity: BMI323+BMM350+BMP581 10DOF IMU Sensor (I2C / UART, Plug & Play)

The DFRobot Gravity: BMI323+BMM350+BMP581 10DOF IMU Sensor is a high-performance motion sensing module designed for precise orientation, motion, and altitude measurement. Combining a 6-axis IMU, 3-axis magnetometer, and high-precision barometric pressure sensor, it delivers reliable acceleration, angular velocity, magnetic heading, pressure, and altitude data in a single compact board. Built-in hardware motion algorithms support step counting, tap, tilt, free-fall, and activity recognition without increasing the host controller workload. Standard I²C and UART interfaces ensure quick plug-and-play integration with Arduino, Raspberry Pi, and ESP32 development boards. Multiple power modes, configurable measurement ranges, and high-speed output rates make it suitable for robotics, drones, wearable devices, navigation systems, and motion tracking applications. The included GUI software enables real-time sensor visualization and easy evaluation without programming.
