j3 0:bb5b832891fb 40 @brief The BMI160 is a small, low power, low noise 16-bit inertial measurement
j3 0:bb5b832891fb 41 unit designed for use in mobile applications like augmented reality or indoor
j3 0:bb5b832891fb 42 navigation which require highly accurate, real-time sensor data.
j3 0:bb5b832891fb 43
j3 0:bb5b832891fb 44 In full operation mode, with both the accelerometer and gyroscope enabled, the
j3 0:bb5b832891fb 45 current consumption is typically 950 μA, enabling always-on applications in
j3 0:bb5b832891fb 46 battery driven devices. It is available in a compact 14-pin 2.5 x 3.0 x 0.8 mm³
j3 0:bb5b832891fb 47 LGA package."
