STEVAL-MKI104V1

MEMS demonstration board based on the LPY403AL

(dual-axis pitch and yaw ±30 dps analog gyroscope)

Features

– analog (AWM)

– digital (DWM)

Description

The STEVAL-MKI104V1 is a demonstration board

designed to provide the user with a complete,

ready-to-use platform for demonstration of the

LPY403AL product family.

The kit 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 uses an ST7 microcontroller

which functions as a bridge between the sensor

and the PC. This makes it possible to download

the graphical user interface (GUI) from the

website or to use dedicated software routines for

customized applications.

The STEVAL-MKI104V1 demonstration board has

been designed for use in two working modes:

analog and digital.

In analog working mode (AWM) the

microcontroller on the board is disabled and the

analog outputs of the device are available to the

user on a dedicated connector. This is the default

working mode when the power supply is applied

either through the USB connector or through the

supply connector.

In digital working mode (DWM) the microcontroller

on the board is enabled and it allows the user to

digitally acquire the output signals of the device,

to see them on the PC through the dedicated

GUI, and to control the control pins of the device.
