IMU381ZA
INERTIAL MEASUREMENT SYSTEM
The IMU381ZA is an improved version of the popular
IMU380ZA
miniature
fully-calibrated
Inertial
Measurement System. The changes include better
gyro
performance,
improved
synchronization
capability, and a bootloader function, which allows
field upgrade-ability and also enables customers to
take advantage of the ACEINNA open source
navigation software development platform.
Features
Complete 6DOF Inertial System
Optional magnetic sensors
SPI (or UART) Interface
Update Rate, 1Hz to 200Hz
Precision Farming
Platform Stabilization
1KHz Clock Sync Input
Miniature Package, 24 x 37 x 9.5 mm
The ACEINNA IMU381ZA integrates highly-reliable MEMS
6DOF inertial sensors (optional 3-axis magnetic sensors) in
a miniature factory-calibrated module to provide consistent
performance through the extreme operating environments
in a wide variety of dynamic control and navigation
applications.

NAV-VIEW provides an easy to use
graphical interface to display, record,
playback, and analyze all of the
IMU381ZA system parameters.
NAV-VIEW can also be used to set a
wide range of user-configurable fields
in the IMU381ZA to optimize the
system performance for highly
dynamic applications.
