Introduction

The SMI230 is a combined triaxial accelerometer (ACC) and triaxial gyroscope (GYR) for non-safety related applications, e.g. for in-dash navigation in the passenger compartment. Within one package, the SMI230 offers the detection of acceleration and angular rate for the x-, y-, and z-axis. The digital standard serial peripheral interface (SPI) of the SMI230 allows for bi-directional data transmission.
