The NIU2A is a compact, rugged, low-power, multifunction Nano Interface Unit. It operates as a standalone Ethernet-connected Remote Interface Unit (RIU) and can be optionally equipped with ARM Cortex-A9 processors to act as an integrated single-board computer (SBC). Here are some key points about the NIU2A:

Multifunctional Capability: It supports up to two NAI smart Configurable Open Systems Architecture™ (COSA®) function modules, making it versatile for various I/O requirements.

Networking Options: The NIU2A comes with standard 10/100/1000Base-T (Gigabit Ethernet) ports. It also offers optional fiber-optic ports for enhanced connectivity.

Power Specifications: It includes an integrated MIL-STD-704F power supply, designed to ensure stable power in demanding environments.

Durability: The unit is designed for rugged industrial, military, and aerospace applications. It is compact, measuring 7.2” x 2.7” x 3.0” and weighs approximately 2.7 lbs (1.22 kg).

Operational Configuration: The NIU2A can be configured via its RS-232 port for maintenance, diagnostics, or interface configuration.

Environmental Suitability: It is well-suited for air, land, and sea applications, optimized for SWaP (Size, Weight, and Power).

Cold Plate Mounting Requirement: For efficient thermal management, the NIU2A must be mounted to a cold plate, ensuring its chassis thermal interface does not exceed 71°C .

Repair and Safety: It contains high-voltage components and should not be opened or repaired by users. All repairs must be conducted at the factory.

These features make NIU2A highly suitable for implementing scalable, network-centric operational architectures across diverse platforms in harsh environments .
