Overview
The
16488HA
Inertial
Measurement
Unit
(IMU)
is
a
fully
integrated
inertial
sensing
system
that
combines
a
three-axis
gyroscope
and
a
three-axis
accelerometer
within
a
compact
module.
It
accurately
measures
three-axis
angular
velocity
and
linear
acceleration
of
the
host
platform.

The
unit
outputs
high-precision
inertial
data
via
an
SPI
digital
interface,
following
a
standardized
communication
protocol,
making
it
ideal
for
embedded
applications
requiring
reliable
motion
sensing
in
dynamic
environments.
