M-G362 Datasheet, PDF (5/69 Pages) Epson Company – IMU (Inertial Measurement Unit)

1. Overview
The M-G362PDC1 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 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
general-purpose SPI/UART support for host communications, the M-G362PDC1 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.
