UT100CA Industrial Motherboard

Name: UT100CA Industrial Motherboard
Brand: GEOLiNK
SKU: UT100CA

Nine Core Ultra SKUs from 125U to 185H, DDR5 up to 96 GB, dual Intel i226 2.5G LAN and dual HDMI 2.1 plus Type-C DP 4K — the UT100CA is the flexible top of the GEOLiNK NUC stack, shipped in the U-BOX-M5 chassis. U-series SKUs trim power draw for sealed boxes; H-series SKUs add threads for compute-heavy jobs — the same board hosts both.

Why UT100CA

Four reasons to start here

CPU

Nine SKUs, one board

Core Ultra 125U to 185H, U and H series, all at 28W — the widest CPU ladder in the NUC family, so one board covers many builds.

Memory

96 GB of DDR5

Two SO-DIMM sockets support 96 GB for virtualization hosts, analytics nodes and memory-hungry edge workloads.

LAN

Dual Intel i226

Two Intel 2.5G controllers as standard, with Wi-Fi, 4G/5G and Bluetooth expansion via the M.2 E-Key slot.

Headers

Two USB 2.0 headers

Two USB 2.0 pin headers plus RS232 — more internal wiring points than the rest of the family for panel and enclosure wiring.

Where It Fits

Machine-adjacent control and desk-side compute

The UT100CA splits the difference between embedded control and workstation-class loads. Typical placements:

Machine-side control: the RS232 header and dual USB 2.0 headers tie into PLC panels, sensors and industrial peripherals inside the cabinet.
Scientific computing: 96 GB DDR5 and 185H-class SKUs handle dense number-crunching and analysis workloads in compact desktop boxes.
Smart embedded systems: the −20/+60°C range and DC 12–19V input suit automation hubs and always-on embedded enclosures.

One board across all nine SKUs means a single qualification, a single stock item and a simpler spare-part strategy.

Configuration

Ordering options

Nine Core Ultra SKUs from 125U to 185H are selectable at order time on one base board. The H-series SKUs share the 28W envelope, so the cooling solution does not change when you step up. Samples are available at one piece; volume pricing applies from ten.
