This is GY-91 MPU9250+BMP280 10DOF Acceleration Gyro 9-Axis Sensor Module. The GY-91 module is a sensor board that integrates multiple sensors, including the MPU9250 and BMP280, offering a variety of functions for measuring different physical quantities. The MPU9250 is a 9-axis motion sensor that includes an accelerometer, gyroscope, and magnetometer. It’s commonly used in applications that require motion tracking, orientation sensing, or gesture recognition. On the other hand, the BMP280 is a barometric pressure sensor that measures atmospheric pressure and temperature, often used in applications like weather monitoring, altitude sensing, and navigation.

Combined, these sensors can provide a range of data including acceleration, angular velocity, magnetic field strength, atmospheric pressure, and temperature. This kind of sensor fusion is valuable in various applications like drones, robotics, navigation systems, and motion-controlled devices, allowing for more comprehensive and accurate data collection for orientation and environmental sensing.


  1. MPU9250: This is a 9-axis sensor combining an accelerometer, gyroscope, and magnetometer. It’s capable of measuring acceleration, angular velocity, and magnetic field in three axes each, providing comprehensive motion sensing capabilities.
  2. BMP280: This is a barometric pressure sensor capable of measuring temperature and atmospheric pressure. It’s useful for altitude estimation, weather monitoring, and more.
  3. 10 Degrees of Freedom (10DOF): The module integrates these sensors to provide accurate data for 10 degrees of freedom, including 3-axis acceleration, 3-axis gyroscope, 3-axis magnetometer, and barometric pressure/altitude.
  4. I2C Interface: The module typically communicates via I2C (Inter-Integrated Circuit) protocol, making it easy to connect and interface with microcontrollers and other devices.
  5. Small Form Factor: Designed as a compact module, it’s suitable for various applications where space is limited but precise motion sensing, orientation tracking, and environmental sensing are required.
