STEVAL-MKI081V1
MEMS demonstration board based on the LPR403AL
(analog output 2-axis gyroscope)
Features
■Two working modes:
– analog (AWM)
– digital (DWM)
■RoHS compliant
Description
The STEVAL-MKI081V1 demonstration board is
designed to provide the user with a complete,
ready-to-use platform for demonstration of the
LPR403AL 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-MKI081V1 demonstration board has
been designed for use in two working modes:
analog and digital.
In analog 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 mode (DWM) the microcontroller on the
board is enabled and 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.
