Bosch BMI270

The device is a highly integrated, low power inertial measurement unit (IMU) that combines precise acceleration and angular rate (gyroscopic) measurement with intelligent on- chip motion- triggered interrupt features. BMI270 integrates: 16- bit digital, triaxial accelerometer with ±2g / ±4g / ±8g / ±16g range 16- bit digital, triaxial gyroscope with ±125 dps/±250dps/±500dps/±1000dps/±2000dps range

• Compact standard size LGA mold package, 14 pins, footprint 2.5x3.0mm² height 0.83mm
• Output data rates (ODR): 25Hz ... 6.4 kHz (gyroscope) and 0.78 Hz ... 1.6 kHz (accelerometer)
