Adafruit BNO055 + BMP280 BFF Add-On for QT Py
The Adafruit BNO055 + BMP280 BFF is a compact add-on board that gives any QT Py or Xiao board powerful 9-degree-of-freedom (9-DoF) motion sensing plus barometric pressure and altitude measurement. It mounts directly onto the back of your QT Py, creating a tiny but capable sensor package.
The BNO055 handles all sensor fusion on-chip, delivering ready-to-use orientation, acceleration, and magnetic field data over I2C without the need for complex algorithms. The BMP280 adds barometric pressure sensing with ±1 hPa accuracy, enabling altitude estimation to ±1 metre. Both sensors communicate via I2C with configurable addresses (BNO055 @ 0x28, BMP280 @ 0x77) and address-changing jumpers.
BNO055 Sensor Outputs
- Absolute Orientation (Euler) – Three-axis orientation on a 360° sphere at 100 Hz
- Absolute Orientation (Quaternion) – Four-point quaternion output at 100 Hz
- Angular Velocity – Three-axis rotation speed in rad/s at 100 Hz
- Acceleration – Three-axis acceleration (gravity + linear motion) in m/s² at 100 Hz
- Linear Acceleration – Three-axis acceleration minus gravity in m/s² at 100 Hz
- Gravity Vector – Three-axis gravitational acceleration in m/s² at 100 Hz
- Magnetic Field Strength – Three-axis sensing in µT at 20 Hz
- Temperature – Ambient temperature at 1 Hz
BMP280 Sensor Outputs
- Barometric Pressure – ±1 hPa absolute accuracy
- Altitude – ±1 metre accuracy derived from pressure
- Temperature – ±1.0°C accuracy
Key Features
- BFF Form Factor – Mounts directly on the back of any QT Py or Xiao board
- On-Chip Sensor Fusion – BNO055 processes 9-DoF data internally
- I2C Communication – Both sensors on the SDA/SCL pins
- Address Jumpers – Configurable I2C addresses for both sensors
- Optional Interrupt/Reset – Additional BNO055 control pins available
- Flexible Mounting – Solder directly or use headers for a removable sandwich
Ideal For
- Compact drone and robotics navigation
- Motion tracking with altitude sensing
- Wearable orientation and altitude projects
- Miniature weather and motion data loggers
