9-Axis Attitude Gyro Accelerator Magnetometer Sensor Module GY-9250 BRD35

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.

Getting started with 9-Axis Attitude Gyro Accelerator Magnetometer GY-9250 and Arduino UNO

Step1: Hardware required

• Arduino UNO
• 9-Axis Attitude Gyro Accelerator Magnetometer GY-9250
• Male to female jumper wire

Step2: Connecting the Hardware

GY-9250                                                                                Arduino UNO

VCC                                        Connected to                                  3.3v

GND                                       Connected to                                  GND

SCL                                         Connected to                                  A5

SDA                                        Connected to                                  A4

Step3: Making the sketch and Testing

To test the Arduino MPU 9250, first download the Arduino library for MPU 9250, you can find it here Next, you have to unzip/extract this library, take the folder named “MPU9250”, and paste it inside the Arduino’s “library” folder. To do this, go to the location where you have installed Arduino (Arduino –> libraries) and paste it inside the libraries folder.

If you have done this correctly, when you open the Arduino IDE, you can see “MPU9250” in File –> Examples. Next, open the example program from File –> Examples –> MPU9250 –> Simple
