Why PX700CA

Four things that stand out on the spec card

CPU

35W Ryzen 7000 series

Up to the Ryzen 7 8845HS — the highest-TDP NUC board in the GEOLiNK family, for builds that need more compute than a 28W board can offer.

LAN

Realtek RTL8125B pair

Two 2.5G controllers for routing and gateway work, with Wi-Fi, 4G/5G and Bluetooth expansion supported alongside.

Video

DP 8K on both Type-C

Each Type-C carries DisplayPort 8K@60Hz plus USB 3.0 — two future-proof video paths that double as high-speed ports.

Expansion

FPC PCIe 4.0 x4 reserved

A reserved FPC interface for PCIe 4.0 x4 devices is on the layout, to be enabled after update and validation in the next release.

Where It Fits

Compute for depots and control rooms

The PX700CA suits installations that want Ryzen-class throughput in a compact, passively friendly footprint. Typical placements:

Depot and station equipment: 35W headroom for ticketing and passenger-information computers, with Wi-Fi, 4G/5G and Bluetooth expansion for the backhaul link.
Industrial control: the −20/+60°C range and DC 12–19V input fit plant-floor enclosures and small control cabinets.
Professional compute: high-thread Ryzen SKUs and 64 GB DDR5 handle dense desktop-style workloads in compact office and workshop machines.

For all three placements the DC 12–19V input and the −20/+60°C operating range are the constants the integrator can rely on.
