STEVAL-MKI080V1

UM0855 User manual Demonstration kit for single and double axis gyroscopes in a 4 x 5 mm package Introduction This document applies to all demonstration kits related to ST MEMS single and double axis gyroscopes in 4 x 5 mm packages, hereafter referred to as STEVAL-MKI0xxV1. The STEVAL-MKI0xxV1 is a demonstration kit designed to provide the user with a complete, ready-to-use platform for demonstration of the LPR4xxAL and LPR4xxxAL product families. The device includes a sensing element and an IC interface capable of translating information from the sensing element into a measured signal that can be used for external applications. In addition to the MEMS sensor, the demonstration board utilizes an ST72651AR6 microcontroller which functions as a bridge between the sensor and the PC, on which it is possible to use the downloadable graphical user interface (GUI), or dedicated software routines for customized applications. This user manual describes the hardware included with the demonstration kit and provides the information required to install and run the demonstration kit user interface. For details regarding the features of each member of the LPR4xxAL and LPR4xxxAL sensor families, please refer to the datasheets available for each single device.
