ISM330BX 6-Axis IMU

STMicroelectronics' ISM330BX is a system in package (SiP) inertial measurement unit (IMU) featuring a 3-axis digital accelerometer and a 3-axis digital gyroscope with triple channels for processing acceleration and angular rate data for motion tracking and vibration measurements along with Qvar sensing on possibly up to three separate channels with dedicated configuration, processing, and filtering.

The motion tracking in high-performance mode runs at 0.6 mA and enables always-on low-power features for an optimal motion experience.
