Inertial Measurement Unit: BMI085
High performance. Optimized for AR and VR.
BMI085
IMU combining accelerometer and gyroscope
BMI085 is a high-performance IMU specifically designed for AR/VR applications. The 6-axis IMU combines a 16-bit tri-axial gyroscope and a 16-bit tri-axial accelerometer featuring low latency and high temperature stability. Providing accurate and reliable motion tracking data even under demanding conditions such as thermal effects like heating this sensor displays maximum performance in minimal size.
Platform stabilization (e.g. image, video)
Navigation
Continuously usable due to always-on low-power speech processing
