Description: 1. MPU-9250 is a 6-Axis Attitude Gyro and Accelerometer sensor module, featuring both gyroscope and accelerometer functions, without the magnetometer component. 2. Functionality: It integrates three-axis gyroscope sensors (ADXL345) and three-axis accelerometer sensors (MPU-6050), providing data for angular velocity (gyro) and linear acceleration (accelerometer). 3. Communication Interface: The module utilizes the I²C communication interface, making it easy to connect multiple sensors using only two wires (SDA & SCL). 4. Digital Motion Processing: MPU-9250 includes digital motion processing features like user-defined axes mapping, self-test, and calibration routines, simplifying sensor setup and usage. 5. Temperature Range: Operating temperature for the MPU-9250 is between 0°C and +40°C, making it suitable for most environments. 6. Output Data Rates: Customizable output data rates allow users to choose between various options (100Hz – 8.5kHz) for optimized performance based on the
