ASUS NUC LAN & USB Add-On Assembly (1x RJ-45, 2x USB 2.0)

The ASUS NUC LAN & USB Add-On Assembly (90AR0000-P00010) is an internal expansion module designed for ASUS NUC mini PCs. It connects via a proprietary header inside the chassis to provide additional ports. The module includes a 1 Gbit/s Gigabit Ethernet port, allowing for stable wired networking in home or office environments without occupying any of the host machine’s existing external ports. As a fixed internal component, it maintains the mini PC’s original, compact footprint.

The module features an RJ-45 LAN port and two USB 2.0 ports. These additional USB ports are suitable for low-bandwidth peripherals such as input devices or printers. Compatibility is limited to specific ASUS NUC models, primarily the taller H-series variants of the 11th, 12th, and 13th generation Pro lines. Installation requires a motherboard with the matching expansion header; the unit draws power directly from the board and functions as a native system component.

• Two USB 2.0 Type-A ports: provides additional peripheral connections for mice and keyboards.
• 10/100/1000 Mbps RJ-45 interface: adds a high-speed wired network connection.
• Proprietary NUC expansion header: connects directly to the motherboard, avoiding the need for external cables.
• Compatible with ASUS NUC11TNH, NUC12WSH, and NUC13ANH: fits specific Pro-series tall chassis models.
• Internal design: maintains the mini PC’s original dimensions and appearance.
