1. Introduction
This document is a detailed guide to use the BNO055 USB stick using the sensor evaluation
environment, Development Desktop from Bosch Sensortec.
The USB stick contains the BNO055 and an MCU which acts as an interface to the USB port.
Figure 1 : BNO055 USB Stick
You can find 2 LEDs in the middle and a switch at one end. The switch is used to control the
modes of operation (see Chapter 5.2).

2. Installation
2.1 Requirements
Following are the minimum requirements for a successful installation:
Windows 7
Installer for Development Desktop 2.0 (UI version 2.8 or higher), which can be downloaded
from this link.
BNO055 USB Stick
Figure 2 : DD 2.0 UI Version printed on the USB Stick
Note: The first version of the BNO055 USB stick (which has a green colored PCB) is not
compatible with USB 3.0 ports. Hence the user could connect the stick over a USB2.0 port.
For usage with USB 3.0 ports, you need to have the updated version of the hardware (red colored
PCB) and the latest version of DD2.0. The working combination of the stick and Development
Desktop’s version will be printed on the PCB as shown above in Figure 2 “DD2.0 UI 3.0 or later”.
2.2 Installation of Development Desktop
Please follow the instructions from the User manual of Development Desktop.
Note: Also ensure that the USB driver is installed (i.e. follow the installation process carefully).

3. Using the BNO055 USB stick
1. Make sure the switch at the end of the USB stick is in position H (see Figure 1 : BNO055
USB Stick) or in ‘lock’ position.
2. Plug the USB stick into the USB port of your PC. The red LED on the stick should glow.
3. Open Development Desktop. You should see the main window as below:
Figure 3 : Main window of Development Desktop
4. On startup, the BNO055 is in CONFIG_MODE. Select an operation mode in the
dropdown to the right of Config Mode or simply disable CONFIG_MODE (refer figure).
5. Once CONFIG_MODE is disabled, you can start streaming as shown below in Figure 4.

6. Check the BNO055 data sheet and the Development Desktop documentation for more
options.
The help file outlining BNO055 use in Development Desktop environment is under :
Help->User Manuals->BNO055 User Manual
7. If you go to Panels and activate 3D Compass a new window opens and displays a 3D object
whose motion is controlled according to the motion of the BNO055.
Please note:
Before you start the 3D Compass, the BNO055 must be set to one of the following fusion modes:
eCompass (accelerometer + magnetometer)
IMU (accelerometer + gyroscope)
9Dof (accelerometer + gyroscope + magnetometer)
3.1 Sensor calibration
The BNO055 must be calibrated before use. Un-calibrated BNO055 stick will deliver data of lower
accuracy. Calibration of magnetometer and gyroscope is crucial.
Calibration procedure:
Gyroscope: Requires a steady state for short moment in order to calibrate itself. Place sensor
on a flat surface for a few seconds.
Magnetometer: The stick must be moved a few times in a figure of 8 or ∞ pattern. You can
have a look at the video here.
Accelerometer: To calibrate the sensor stick must be placed in six different steady positions.
This step can be omitted, since the offsets of the accelerometer channels are small and have
no negative impact on the data accuracy of the fused data.
