GY-91 MPU6500 + BMP280 7DOF IMU & Barometric Pressure Sensor Module
GY-91 MPU6500 + BMP280 7DOF IMU & Barometric Pressure Sensor Module
The GY-91 module combines an MPU6500 6-axis IMU with a BMP280 barometric pressure and temperature sensor. It is suitable for motion sensing, orientation detection, altitude-related projects, robotics and flight-control experiments.
Important: This version of the module does not have a magnetometer. It cannot measure magnetic field or provide a compass heading. It should not be used where a 9-axis/10DOF compass sensor is required.
Key Features
- MPU6500: 3-axis accelerometer and 3-axis gyroscope
- BMP280: barometric pressure and temperature sensing
- 7DOF sensor combination: 6-axis motion sensing plus barometric pressure
- I2C and SPI communication support
- Onboard voltage regulation for convenient module power input
- Compact board for Arduino, ESP32, STM32, Raspberry Pi and compatible controllers

Important Usage Notes
- Use 3.3V logic levels for sensor communication unless your controller board provides verified level shifting.
- This is a bare sensor module; it is not a complete flight controller.
- For magnetic heading or compass functions, choose a module that explicitly includes a magnetometer.
