Bosch Sensortec – BMI160 low power inertial measurement unit
The BMI160 is a small, low-power, low-noise 16 bit Inertial Measurement Unit designed for use in mobile applications such as augmented reality or indoor navigation which require highly accurate, real-time sensor data. In full operation mode, with both the accelerometer and gyroscope enabled, the current consumption is typically 925 μA, enabling always-on applications in battery driven devices. It is available in a compact 14-pin 2.5 × 3.0 × 0.8 mm³ LGA package.
