GY-91 MPU9250 + BMP280 10DOF Multi-Sensor Module
All-in-One Motion, Orientation, Altitude, and Temperature Sensing
The GY-91 10DOF sensor module combines the powerful MPU9250 (3-axis accelerometer, 3-axis gyroscope, 3-axis magnetometer) and the high-precision BMP280 barometric pressure sensor into a single, compact breakout board. Designed for advanced motion tracking and environmental monitoring, it gives microcontrollers complete spatial awareness—measuring tilt, rotation, magnetic heading, altitude, pressure, and ambient temperature simultaneously.
10 Degrees of Freedom: Integrates a 9-axis IMU (gyro + accelerometer + compass) and a precision altimeter/barometer on one board.
Dual Communication Interfaces: Supports both I2C and SPI protocols for easy connection to Arduino, ESP32, STM32, and Raspberry Pi.
High-Precision Flight & Navigation: Perfect for drone flight controllers, autonomous robotics, indoor positioning systems, and rocket telemetry.
Built-in Voltage Regulation: Operates safely on 3.3V to 5V power with on-board logic level translation.
Specifications:
Supply Voltage: 3.0V – 5.0V DC
