IMU 10 DOF AHRS BNO055 + BMP280 Gravity

Merupakan 10 DOF IMU AHRS (Altitude and Heading Reference System) yang menggabungkan Sensor IC BNO055 dan BMP280 kedalam 1 modul. BNO055 sendiri sensor IMU 9 DOF yang mengkombinasikan 3-axis 14-bit accelerometer, 3-axis 16-bit gyroscope, 3-axis geomagnetic sensor serta 32-bit mikrokontroller. Sedangkan BMP280 adalah barometric pressure dan temperature. IMU 10 DOF AHRS BNO055 + BMP280 Gravity menggunakan antarmuka I2C sehingga memudahkan pengguna untuk menghubungkan ke mikrokontroller.
