MPU9250 + BMP280 10DOF Acceleration Gyroscope Compass Nine Shaft Sensor Module GY91 Why this module matters Combines a 9axis motion sensor (MPU9250) with a pressure/temperature sensor (BMP280) to deliver 10 degrees of freedom (10DOF) in a single compact module. Provides motion, orientation and environmental data together so you can measure acceleration, angular velocity, magnetic heading, barometric pressure and temperature from one board. Ideal when you need a single, integrated sensor package to simplify wiring, software integration, and sensor fusion for realtime applications. Key benefits Allinone sensing: Eliminates the need to mount and synchronize separate IMU and barometer boards. Faster development: Use existing MPU9250 and BMP280 libraries and sensor fusion algorithms to accelerate prototyping. Space and weight savings: Compact module form factor reduces enclosure and mounting complexity for embedded and mobile projects. Versatile data: Enables both motion tracking and altitude/pressure sensing for richer situational awareness. Core functionality and attributes Sensors included: MPU9250 (accelerometer, gyroscope, magnetometer) and BMP280 (barometric pressure and temperature). Degrees of freedom: 10DOF (9axis motion + barometric pressure/temperature). Model / module: GY91 sensor module. Typical use: Motion tracking, orientation sensing, magnetic heading, barometric pressure/altitude sensing and ambient temperature measurement. Design: Integrated sensor module that consolidates motion and environmental sensing in one board. How it solves common problems Avoids synchronization issues between separate IMU and barometer boards by providing colocated sensors on a single module. Reduces wiring and board space, simplifying assembly for drones, robotics, and wearable devices. Supports sensor fusion approaches that combine motion and pressure data for more accurate altitude estimation and orientation stabilization. Applications and use cases Drones and multirotors: Use combined IMU and barometer data for attitude stabilization, heading control and altitude hold. Robotics and navigation: Provide orientation, heading and altitude information for autonomous robots, UGVs or mobile platforms. Portable sensing and prototyping: Integrate into handheld devices, data loggers or wearables that require motion tracking and environmental pressure/temperature sensing. Integration notes (practical considerations) The module brings together the MPU9250 and BMP280 sensors so you can reuse common drivers and sensor fusion libraries for faster integration. Suitable for projects that require synchronized motion and pressure measurements without separate sensor assemblies. What makes it unique The GY91 module pairs a full 9axis IMU with a resolution barometric sensor, delivering a compact 10DOF solution that addresses both motion and environmental sensing needs in a single component. this module when you want a compact, integrated sensor solution that simplifies development of orientation, motion and altitudeaware applications.
