The Adafruit BNO055 + BMP280 BFF (Best Friend Forever) is designed to augment QT Py or Xiao boards, providing powerful 9 degree-of-freedom (9DoF) motion plus pressure/altitude sensing capabilities in a compact form factor. This board enhances the capabilities of QT Py boards, offering sensor fusion capabilities and precise barometric pressure measurements.

Features:

1. Enhanced Sensor Capabilities: Combines the BNO055 9-DOF sensor for motion sensing with the BMP280 precision sensor for barometric pressure and temperature sensing, providing comprehensive environmental data.
2. Easy Integration: Designed to fit onto the back of any QT Py or Xiao board, this PCB can be soldered into place or made removable using pin and socket headers.
3. Sensor Fusion: The BNO055 sensor performs sensor fusion internally, providing meaningful sensor data over I2C without the need for complex algorithms.
4. Versatile Data Output: Outputs various sensor data including Absolute Orientation (Euler Vector and Quaternion), Angular Velocity Vector, Acceleration Vector, Magnetic Field Strength Vector, Linear Acceleration Vector, Gravity Vector, and Temperature.
5. Barometric Pressure Sensing: The BMP280 sensor offers 1 hPa absolute accuracy for barometric pressure measurements, enabling precise altitude calculations with 1 meter accuracy.
