This compact Gravity module combines a Bosch BNO055 absolute orientation sensor with a BMP280 barometric pressure and temperature sensor to create a 10DOF AHRS module for motion, heading and environmental sensing.
The BNO055 integrates a triaxial 14-bit accelerometer, triaxial 16-bit gyroscope, triaxial geomagnetic sensor and a 32-bit microcontroller, allowing it to output both raw sensor data and fused orientation data such as quaternions, Euler angles and vectors. The BMP280 adds barometric pressure and temperature measurement, with pressure data suitable for altitude calculations using the appropriate formula.
The standard Gravity-I2C interface helps simplify integration into Gravity-compatible projects, including wearable hardware, augmented reality, immersive gaming, personal health and fitness, indoor navigation and other context-aware applications. DFRobot provides a product wiki, and the package includes the Gravity BNO055+BMP280 intelligent 10DOF AHRS(V1.0) Module x1 and Gravity 4Pin I2C/UART Sensor Cable x1.

Jargon buster
Plain-language definitions for the technical terms used above.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- Gyroscope
- A gyroscope measures rotation, such as how fast a board is turning around its X, Y, and Z axes. This matters for projects like gesture controls, balancing robots, and motion tracking where tilt or rotation changes need to be detected.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
