Inertial Measurement Unit: BMI323
Easy to use. Accurate. Low power.
BMI323
IMU combining accelerometer and gyroscope
For all that want to get the maximum out as quickly as possible, the BMI323 Inertial Measurement Unit (IMU) is the right choice. As an all-rounder it convinces with its wide range of use cases: angle & position detection enables fast laptop booting or the automatic adjustment of settings. Motion detection lets toys come to life for a unique gaming experience and the step counting function is the ideal companion in everyday life. BMI323 can be used in notebooks & tablets, toys & gadgets, game controllers & smart remote controls, in wearables and more. The IMU is easy-to-use due to integrated features and configurable power modes.The BMI323 is a general purpose, low-power IMU that combines precise acceleration and angular rate (gyroscopic) measurement with intelligent on-chip motion-triggered interrupt features. The 6-axis IMU comprises a 16-bit triaxial gyroscope, a 16-bit triaxial accelerometer, and a 16-bit digital temperature sensor in a miniature 2.5 x 3.0 x 0.83 mm³ (14-pin) LGA package.
