Brand: Adafruit
Category: Breakout Board

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.


  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.


  1. BNO055 Sensor Data Output:
    Absolute Orientation (Euler Vector, 100Hz)
    Absolute Orientation (Quaternion, 100Hz)
    Angular Velocity Vector (100Hz)
    Acceleration Vector (100Hz)
    Magnetic Field Strength Vector (20Hz)
    Linear Acceleration Vector (100Hz)
    Gravity Vector (100Hz)
    Temperature (1Hz)
  2. BMP280 Sensor Data Output:
    Barometric Pressure with ±1 hPa absolute accuracy
    Temperature with ±1.0°C accuracy
  3. Communication Interface: I2C
    Optional Interrupt/Reset Pins for BNO055 for advanced control
    Address-changing jumpers for both sensors to switch from default addresses (BMP280 @ 0x77 and BNO055 @ 0x28)
  4. Compatibility: Compatible with QT Py and Xiao boards with I2C communication capability
