Overview

The Compact Rugged IMU VN-100 is a versatile inertial measurement unit designed for applications where space, weight, and reliability are critical. Available in both SMD and rugged versions, it provides high-quality motion data for drones, robotics, defence systems, and industrial machinery. With its fast update rates, factory calibration, and flexible interfaces, the VN-100 is well-suited for stabilisation, motion tracking, and control in demanding environments.

Key Features

• Compact footprint: Ideal for tight spaces and embedded designs.
• Two versions: SMD for PCB mounting and rugged for harsh environments.
• Accurate 3-axis inertial sensing: Measures acceleration and rotation on all axes.
• Fast update rates: Supports real-time stabilisation and motion control.
• Easy integration: Interfaces designed for drones, robots, and machine systems.
