PNM-5210 Industrial Motherboard

Name: PNM-5210 Industrial Motherboard
Brand: GEOLiNK
SKU: PNM-5210

A 15W Intel N150/N305 platform that fronts as a network appliance: four 2.5G LAN ports with PoE power-sourcing, a SIM slot for 4G/5G failover, five serial channels and wide DC 9–36V input — all squeezed into a 120×120 mm NANO board.

Why PNM-5210

A NANO board that behaves like an appliance

Port Density

Four 2.5G LAN ports

3× Intel i226-V plus 1× RTL8156B — enough copper for WAN/LAN/DMZ segmentation on a single 120 mm board, no PCIe riser required.

PoE Out

48V/15W PSE

PoE power-sourcing equipment (IEEE 802.3af) lets the board feed remote cameras and sensors straight from the LAN ports.

Wide Input

DC 9–36V, no converter

Battery banks, vehicle rails and solar-fed power all land inside the input range — fewer external bricks, simpler BOMs for system integrators.

Connectivity

SIM + Mini PCIe expansion

A dedicated SIM slot with Mini PCIe (PCIe + USB 2.0 + SATA 3.0) for 4G/5G modules, plus five COM ports for serial peripherals.

Where It Fits

Gateway racks and hardened comms

The PNM-5210 earns its keep wherever network density, wide input and serial reach have to share one board. Typical deployments:

Industrial IoT gateways: four LAN segments for field devices plus a SIM-backed cellular uplink, all monitored through the RJ45 console port.
Security appliances: PoE out to feed edge cameras, 9–36V input from site batteries, and 5× COM for door controllers and alarms.
Utility comms cabinets: wide-voltage tolerance for 24V substation rails and storage down to −20°C, with RS485 BOM legs to metering stacks.
