Adafruit BNO055 + BMP280 BFF Add-On for QT Py

Our QT Py boards are a great way to make very small microcontroller projects that pack a ton of power - and now we have a way for you to turn many QT Py boards into powerful 9 degree-of-freedom (9DoF) motion plus pressure/altitude sensing projects that are super small!

We call this the Adafruit BNO055 + BMP280 BFF—a "Best Friend Forever."  When you were a kid, you may have learned about the "buddy" system; well, this product is kind of like that! It's a board that will watch your QT Py's back and give it more capabilities.

This PCB is designed to fit onto the back of any QT Py or Xiao board. It can be soldered into place or made removable using pin and socket headers.

Rather than spending weeks or months fiddling with algorithms of varying accuracy and complexity, you can have meaningful sensor data in minutes thanks to the BNO055. This smart 9-DOF sensor does the sensor fusion all on its own!  You can read the data right over I2C and Bob's yer uncle.

The BNO055 can output the following sensor data:

• Absolute Orientation (Euler Vector, 100Hz) Three axis orientation data based on a 360° sphere
• Absolute Orientation (Quaternion, 100Hz) Four point quaternion output for more accurate data manipulation
• Angular Velocity Vector (100Hz) Three axis of 'rotation speed' in rad/s
• Acceleration Vector (100Hz) Three axis of acceleration (gravity + linear motion) in m/s^2
• Magnetic Field Strength Vector (20Hz) Three axis of magnetic field sensing in micro Tesla (uT)
• Linear Acceleration Vector (100Hz) Three axis of linear acceleration data (acceleration minus gravity) in m/s^2
• Gravity Vector (100Hz) Three axis of gravitational acceleration (minus any movement) in m/s^2
• Temperature (1Hz) Ambient temperature in degrees celsius
