The GY-BNO055 module is a compact and intelligent solution for measuring absolute orientation in three-dimensional space, intended for robotics projects, navigation systems, wearable devices, and industrial applications that require high-precision motion data. What sets it apart from conventional sensors is its ability to perform sensor fusion directly on-chip, eliminating the need for complex algorithms implemented in software.
The module integrates a 14-bit triaxial accelerometer, a 16-bit triaxial gyroscope with a measurement range of up to 2000 degrees per second, a triaxial geomagnetic sensor, and an ARM Cortex-M0+ microcontroller running Bosch Sensortec fusion software, all in a single 3.8mm x 5.2mm x 1.1mm. LGA package. Power supply is flexible, supporting voltages between 3V and 5V thanks to the internal voltage regulator, making it directly compatible with Arduino UNO, Arduino Mega, STM32, ESP32, and other popular development platforms without additional voltage adaptation circuits.
Communication is carried out via standard I2C or UART protocol, and the I2C interface can be configured for HID-I2C, turning the module into a plug-and-play sensor for Windows 8.0 and 8.1. devices. The SCL\Rx and SDA\Tx pins are dual-purpose, functioning either in I2C mode or UART mode depending on the configuration of the BOOT and REST pins. The module’s compact dimensions of 12mm x 21mm make integration into tight spaces easier.
The BNO055 can provide the following types of data: absolute orientation as an Euler vector at 100Hz, absolute orientation as a quaternion at 100Hz for more precise calculations, angular velocity in rad/s at 20Hz, total acceleration vector (gravity + linear motion) in m/s² at 100Hz, magnetic field strength in microtesla at 100Hz, linear acceleration (without the gravitational component) at 100Hz, gravitational vector at 100Hz, and ambient temperature in degrees Celsius at 1Hz.

Pinout:
| Pin | Signal | Description |
|---|---|---|
| VIN | Power supply | 3V - 5V DC |
| GND | Ground | Common ground |
| SCL / Rx | I2C / UART | I2C clock line or RX for UART |
| SDA / Tx | I2C / UART | I2C data line or TX for UART |
| ADD | Address | I2C address selection (GND = 0x28 / VCC = 0x29) |
| INT | Interrupt | Interrupt output (active high) |
| BOOT | Boot mode | Startup operating mode selection |
| REST | Reset | Chip reset (active low) |
Usage:
Connect the VIN pin of the module to the 3.3V or 5V pin of the development board and the GND pin to common ground.
For I2C mode: connect SCL\Rx to the board’s SCL pin (e.g. A5 on Arduino UNO, GPIO22 on ESP32, PB6 on STM32) and SDA\Tx to the SDA pin (e.g. A4 on Arduino UNO, GPIO21 on ESP32, PB7 on STM32).
For UART mode: connect SCL\Rx to the development board’s TX and SDA\Tx to the board’s RX. Configure the BOOT and REST pins accordingly to enable this mode.
Leave the ADD pin unconnected or connected to GND for the default I2C address 0x28. Connect it to VIN for address 0x29 if you are using two modules on the same I2C bus.
The INT pin can be connected to a digital pin on the board to detect motion events via hardware interrupts, reducing processor load.
Install the "Adafruit BNO055" library from the Arduino IDE Library Manager (Sketch > Include Library > Manage Libraries).
Also install the "Adafruit Unified Sensor" library, which is required as a dependency.
Upload the test sketch, compile it, and upload it to the board.
Open the Serial Monitor at 115200 baud to view orientation data in real time.
Place the module on a flat surface for initial calibration. Rotate it slowly in all directions to calibrate the magnetometer (figure-eight motions in the air).
Check the calibration status using the sys, gyro, accel, and mag values returned by the getCalibration() function. A value of 3 for each indicates full calibration.
