NIU1A
Nano Interface Unit
Configure with one I/O or communication function module—
Over 100 different modules to choose from
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.
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.

The NIU1A includes BSP and SDK support for Wind River® VxWorks® / Linux and Xilinx® PetaLinux tools. In addition, software support kits are supplied, with source code and board-specific library I/O APIs, to facilitate system integration. Each I/O function has dedicated processing, unburdening the SBC from unnecessary data management overhead.
Background Built-In-Test (BIT)
BIT continuously monitors the status of all I/O during normal operations and is totally transparent to the user. SBC resources are not consumed while executing BIT routines. This simplifies maintenance, assures operational readiness, reduces life-cycle costs and— keeps your systems mission ready.
The NIU1A includes SSKs to support multiple operating systems. In addition, SSKs are supplied with source code and board-specific library I/O APIs to facilitate system integration.
NAI’s Configurable Open Systems Architecture™ (COSA®) offers a choice of over 70 smart I/O, communication, and Ethernet switch functions, providing the highest packaging density and greatest flexibility of any multifunction I/O board in the industry. Preexisting, fully-tested functions can be combined quickly and easily in an unlimited number of ways. Each I/O function has dedicated processing, unburdening the system Single Board Computer (SBC) from unnecessary data management overhead.
