IMU (Inertial Measurement Unit)

GENERAL DESCRIPTION

The M-V340-xx is a small form factor inertial measurement unit (IMU) with 6 degrees of freedom: triaxial angular rates and

linear accelerations, and provides high-stability and high-precision measurement capabilities with the use of high-precision

compensation technology. A variety of calibration parameters are stored in a memory of the IMU, and are automatically

reflected in the measurement data being sent to the application after the power of the IMU is turned on. With a

general-purpose SPI/UART supported for host communication, the M-V340-xx reduces technical barriers for users to

introduce inertial measurement and minimizes design resources to implement inertial movement analysis and control

applications.

The features of the IMU such as high stability, high precision, and small size make it easy to create and differentiate

applications in various fields of industrial systems.
