STEVAL-MKI005V1
demonstration kit for the LIS3LV02DL
Introduction
The STEVAL-MKI005V1 is a demonstration kit designed to provide the user with a
complete, ready-to-use platform to demonstrate the LIS3LV02DL low power 3-axis linear
accelerometer with digital output. 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 features an ST7-USB
microcontroller that functions as a bridge between the sensor and the PC, on which it is
possible to use the graphical user interface (GUI) downloadable from the web site, 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 the LIS3LV02DL sensor, please refer to the datasheet
for this device and application note AN2381.

1 Demonstration kit description
The STEVAL-MKI005V1 is a complete demonstration kit which allows users to evaluate the
performance of the LIS3LV02DL low power 3-axis linear accelerometer with digital output.
The block diagram of the demonstration kit is shown in Figure 1.
Figure 1. Demonstration board block diagram
The ST7-USB microcontroller included on the board allows communication between the
sensor device and the PC. The user can interact with the hardware either through the GUI
provided with the kit, or through dedicated software routines to run customized applications.
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 Figure 2 and
Figure 3.

Operation of the STEVAL-MKI005V1 demonstration kit requires the installation of a
dedicated driver which is included on the installation pack, together with a GUI interface
which allows simple interaction with the sensor. The steps required for driver and software
installation are described in the following section.

2 STEVAL-MKI005V1 GUI installation
The installation of the graphical user interface (GUI) for the STEVAL-MKI005V1 requires two
steps:
1. installation on the PC the software downloaded to EK web page.
2. installation of the Virtual COM driver needed to use the demonstration kit board.
2.1 PC system requirements
Both the hardware and software that compose the STEVAL-MKI005V1 demonstration kit
have been designed to operate with Microsoft®Windows XP and Microsoft®Windows Vista.
2.2 Software installation
To install the software downloaded to EK web page:
1. double-click on “Setup.exe”
2. follow the on screen instructions (Figure 4)

2.3 Hardware installation
To install the virtual COM driver, insert the demonstration kit board into a free USB port. The
“Notify” icon should appear as in Figure 5.
Figure 5. Notify icon
If the “Hardware Update Wizard” window appears (Figure 7), follow the instructions on the
screen. Otherwise, the installation can be performed by following the instructions indicated
in Figure 6 and Figure 7.

Once the installation is complete, a COM port number is assigned to the ST Virtual COM
driver (Figure 8). This number should be retained as it is required to run the STEVAL-
MKI005V1 demonstration software GUI. For additional details, see section 3.1.
