MPU9250 9-Axis Attitude +Gyro+ Accelerator+Magnetometer Sensor Module

Adds a three-axis magnetometer to the six axes of an MPU6050, and that third sensor changes what is possible. A gyroscope and accelerometer alone can track tilt but cannot tell which way is north, so heading slowly drifts. The magnetometer provides an absolute compass reference that corrects it, giving stable orientation in all three axes indefinitely. Essential for drone navigation, AHRS systems and any project needing reliable heading. Nine axes give drift-free absolute orientation; Magnetometer provides true compass heading; Selectable ranges for all three sensor types; I2C or SPI interface, both supported
