Datasheet

The BMX160 9-axis sensor from Bosch is in stock at Mouser Electronics. The compact, power-efficient sensor combines Bosch’s advanced accelerometer, gyroscope and geomagnetic sensor technologies to deliver a solution for a wide range of applications such as smartphones, 3D scanning, fitness trackers, gaming, and augmented reality (AR) and virtual reality (VR) devices.

The sensor incorporates a 16-bit digital, triaxial accelerometer; 16-bit digital, triaxial gyroscope; and triaxial geomagnetic sensor to accurately measure orientation and detect motion in nine degrees of freedom (DoF). It offers acceleration ranges of ±2g to ±16g and gyroscopic range up to 2,000 degrees per second (°/s).

Optimised for low offset, low noise and best temperature stability, the sensor offers an extremely low drift for accurate real-time user experience.

A built-in power management unit and ultra-low-power background application features enable the application processor to remain in sleep mode much longer.

With a typical current consumption of only 1580μA, the sensor is ideal for always-on applications in battery-driven devices.

The device is pin- and register-compatible with the Bosch BMI160 inertial measurement unit (IMU), simplifying integration into existing designs, and comes factory calibrated and ready to use in a compact 2.5 × 3.0 × 0.95mm package.

For development, the BMX160 shuttle board enables designers to gain easy access to the sensor's pins via a simple socket.
