STMICROELECTRONICS STEVAL

STEVAL-MKI104V1
MEMS demonstration board based on the LPY403AL
(dual-axis pitch and yaw ±30 dps analog gyroscope)
Data brief
Features
■
Two working modes:
– analog (AWM)
– digital (DWM)
■
RoHS compliant
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.
STEVAL-MKI104V1
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.
