CEVA BNO08x 9-Axis IMUs

CEVA BNO08x 9-Axis IMUs integrate a triaxial accelerometer, gyroscope, magnetometer, and a 32-bit ARM® Cortex™-M0+ microcontroller operating on CEVA's SH-2 firmware.

The SH-2 includes the MotionEngine™ software, which provides sophisticated signal processing algorithms to process sensor data and deliver:

•  Precise real-time 3D orientation
•  Heading
•  Calibrated acceleration
•  Calibrated angular velocity and more advanced contextual outputs

The CEVA BNO08x IMUs are compatible with Android and supply a turn-key sensor hub solution, eliminating the complexity and investment of a discrete design. The BNO08x features an enhanced sensor fusion algorithm that enables add-on host-based software products for AR/VR and other specialized markets. The BNO086 may be a drop-in replacement for the BNO085, with an identical pinout and software feature set. The BNO086 additionally improves the BNO085, offering 14-bit accelerometer fusion, reducing idle state power, and interactive calibration.

The BNO08x is housed in a 28-pin LGA 3.8mm x 5.2mm x 1.1mm package.
