Introduction

The SMI330 is a highly integrated, low power inertial measurement unit (IMU) that combines precise acceleration and angular rate (gyroscopic) measurement with intelligent on-chip motion-triggered interrupt features. The SMI330 integrates a 16 bit digital, triaxial accelerometer with range configurable to +/- 2 g, +/- 4 g, +/- 8 g, +/- 16 g, a 16 bit digital, triaxial gyroscope with range configurable to +/- 125 DPS, +/- 250 DPS , +/- 500 DPS, a 16 bit digital temperature sensor for an operating temperature range -40 C ... +125 C
