Castor IMU 1640
Miniature 6DOF IMU (OEM PCB Mounted) with SPI Interface
Overview
The Castor series IMU1640 is a high-end tactical-class inertial measurement unit consisting of a high-performance triaxial MEMS accelerometer and triaxial gyroscope built on the latest MEMS technology. A high-speed onboard processor runs superior digital signal processing algorithms to deliver control-grade inertial measurement data over a digital SPI interface.
The sensing elements of each axis are factory-calibrated for bias and misalignment and are temperature-compensated to remain usable across the full operating range. The IMU is designed to be mounted firmly on the customer's own PCB, and its rugged, modular design makes it suitable for integration with control computers and other application hardware where size is a constraint.
