Why UT100NU

Core Ultra where nothing else fits

Platform

28W Meteor Lake onboard

Core Ultra 5 125H or Ultra 7 155H on UEFI firmware — the strongest CPU this 120 mm form factor carries, for inference-adjacent edge and vision workloads.

Memory

DDR5-5600, up to 96GB

Two SO-DIMM slots at 5600 MHz give virtualized edges and analytics boxes the same memory headroom as a 170 mm board.

Networking

Dual i226-V 2.5G

Two adaptive Intel 2.5G controllers, 4× USB 3.0 and a Type-C — enough pipe for camera streams and control traffic on separate networks.

Field Service

One-key restore, AT/ATX

A dedicated RST one-key restore path plus REST_SEL and AT/ATX jumpers let integrators define power-on and recovery behavior for unattended sites.

Where It Fits

Edge inference and dense I/O pods

The UT100NU is for workloads that used to need a Mini-ITX: local AI inference, multi-stream vision and virtualization, now available in a 120 mm board. Typical deployments:

Edge vision boxes: Core Ultra for on-prem image inference, dual 2.5G to carry camera feeds, 96GB for large model footprints.
Security gateways: six serial channels for access panels and alarms, GPIO for door strikes, Type-C for local maintenance.
Industrial PC replacements: DB9 COM to legacy PLCs and instruments while HDMI 2.1 and DP 2.1 drive dual 4K operator screens.
