Demonstration kit for single and
double axis gyroscopes in a 5 x 5 mm package
Introduction
This document applies to all demonstration kits related to ST MEMS single and double axis
gyroscopes in 5 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 LPR5xxxAL, LPY5xxxAL, LY5xxxALH
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 LPR5xxxAL, LPY5xxxAL,
LY5xxxALH sensor families, please refer to the datasheets available for each single device.

Demonstration kit description
The STEVAL-MKI0xxV1 is a complete demonstration kit that allows evaluation of the
performance of the LPR5xxxAL, LPY5xxxAL, LY5xxxALH low-power double/single-axis
gyroscopes with analog outputs.
The block diagram of the demonstration board included in the kit is shown in
Figure 1.

The analog outputs of the device are directly available through a dedicated connector. The
ST72651AR6 microcontroller included on the board acquires and converts the analog
outputs into digital signals, and provides the data to the user on the PC through the GUI
provided with the kit.
The device firmware upgrade (DFU) is a feature allowing users to upgrade the firmware of
the ST7 microcontroller whenever a new firmware release is available on
www.st.com.
Switches and LED indicators are used to control and monitor the functionality of the board.
The top silk screen view and photo of the full board, respectively, are shown in
