Embedded I/O System – NIU1A Nano Interface Unit

North Atlantic Industries

NAI’s NIU1A is a nano unit with an integrated power supply, one function module slot, and an optional ARM Cortex A9 processor. This small, low-power I/O unit is ideally suited for rugged military, industrial, and commercial applications, and delivers off-the-shelf solutions that accelerate deployment of SWaP-optimized systems — in less time, with NO NRE.

Versatile Architecture
The NIU1A provides embedded computing capability via an integrated SoC dual ARM Cortex-A9 processor to add distributed network sensor data interfaces to mission-critical computers without expensive chassis or backplane redesign. The NIU1A delivers ARM processing, Gig-E interfaces and configurable I/O or communications, all in the industry’s smallest package.

NAI's modular, highly configurable Custom-On-Standard-Architecture™ (COSA™) enables you to meet your most demanding system requirements out-of-the-box. Pre-existing, fully-tested functions can quickly and easily be selected to meet system requirements. Individually dedicated I/O and communications processors allow mission computers to manage, monitor, and control the functions via single or dual Ethernet ports.

The NIU1A is designed to operate under extreme temperature, shock, vibration, and EMI environments.
