It's a board that will watch your QT Py's back and give it more capabilities.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\u003eRather 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.\u003c\/p\u003e\n\u003cp\u003eThe BNO055 can output the following sensor data:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAbsolute Orientation (Euler Vector, 100Hz) Three-axis orientation data based on a 360° sphere\u003c\/li\u003e\n\u003cli\u003eAbsolute Orientation (Quaternion, 100Hz) Four-point quaternion output for more accurate data manipulation\u003c\/li\u003e\n\u003cli\u003eAngular Velocity Vector (100Hz) Three-axis of 'rotation speed' in rad\/s\u003c\/li\u003e\n\u003cli\u003eAcceleration Vector (100Hz) Three axis of acceleration (gravity + linear motion) in m\/s^2\u003c\/li\u003e\n\u003cli\u003eMagnetic Field Strength Vector (20Hz) Three axis of magnetic field sensing in micro Tesla (uT)\u003c\/li\u003e\n\u003cli\u003eLinear Acceleration Vector (100Hz) Three axis of linear acceleration data (acceleration minus gravity) in m\/s^2\u003c\/li\u003e\n\u003cli\u003eGravity Vector (100Hz) Three axis of gravitational acceleration (minus any movement) in m\/s^2\u003c\/li\u003e\n\u003cli\u003eTemperature (1Hz) Ambient temperature in degrees celsius\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe only thing it doesn't have is barometric pressure, which can be used for altitude calculations. Aha, that's why there's also a BMP280 sensor on board. This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accuracy.\u003c\/p\u003e\n\u003cp\u003eUsage for the BFF is simple is simple, because both the BNO and BMP talk over I2C - so you'll just use the SDA\/SCL pins. Note that some QT Py boards with a Stemma QT port have two I2C ports, so make sure you are using the port that's on the SDA\/SCL pins, not the QT port! There are optional Interrupt\/Reset pins for the BNO055 if you want more advanced control, and each sensor also has address-changing jumpers in case you want to switch from the default addresses of BMP280 @ 0x77 and BNO055 @ 0x28.\u003c\/p\u003e\n\u003cp\u003eIf you'd like, you can solder the BFF directly on the back of your Xiao\/QT Py or use the included header to solder each side to your QT Py to make a sandwich.
