Nano Interface Unit - NIU1A

Configure with one I/O or communication function module—
Over 70 different modules to choose from


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

Adaptable Architecture

NAI's modular, Configurable Open Systems Architecture™ (COSA®) enables you to meet your most demanding system requirements out-of-the-box. Preexisting, 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.

All products are designed to operate under extreme temperature, shock, vibration, and EMI environments. EMI filters and gaskets meet or exceed MIL-STD-461F and MIL-STD-810G requirements.

Board Support Package (BSP) and Software Support (SSK)

The NIU1A includes BSP and SSK support for Wind River® Linux and VxWorks®, and for Xilinx® PetaLinux (w/optional ARM Processor). In addition, SSKs are supplied with source code and board-specific library I/O APIs to facilitate system integration.
