Overview
The BNO055 USB-STICK, produced by Bosch Sensortec, is a comprehensive evaluation tool designed to facilitate the development and testing of the BNO055 intelligent 9-axis absolute orientation sensor. This USB stick integrates the BNO055 sensor and a microcontroller (MCU) that acts as an interface to the USB port, enabling seamless communication with a host computer. The BNO055 itself is a System in Package (SiP) that combines a triaxial 14-bit accelerometer, a triaxial 16-bit gyroscope, and a triaxial geomagnetic sensor, all managed by a 32-bit Cortex M0+ microcontroller running Bosch Sensortec's sensor fusion software.
