9-Axis Attitude Gyro Accelerator Magnetometer Sensor Module GY-9250

  • RM47.70

  • Ex Tax: RM45.00
  • Product Code: GY-9250
  • Availability: In Stock

 

 

The MPU-9250 is a 9-axis motion tracking device that combines a 3-axis gyroscope, 3-axis accelerometer, 3-axis magnetometer and a Digital Motion Processor™ (DMP) all in a small board available as a pin-compatible upgrade from the MPU-6515. With its dedicated I2C sensor bus, the MPU-9250 directly provides complete 9-axis MotionFusion™ output. The MPU-9250 MotionTracking device, with its 9-axis integration, on-chip MotionFusion™, and run-time calibration firmware, enables manufacturers to eliminate the costly and complex selection, qualification, and system level integration of discrete devices, guaranteeing optimal motion performance for consumers. MPU-9250 is also designed to interface with multiple non-inertial digital sensors, such as pressure sensors, on its auxiliary I2C port.

Q & A

What is the difference between MPU-6050?

The biggest difference between the MPU-6050 and the 9250 is the presence or absence of a geomagnetic sensor.
As the MPU-6050 does not include a geomagnetic sensor, there is an error in the yaw direction which is horizontal to the ground.

On the other hand, because the MPU-9250 includes a geomagnetic sensor, it can extract the exact angle in the yaw direction.
You can choose 6050 or 9250 according to the need of yaw direction.
