2.5GbE PCIe NIC mod board

A tiny 2.5 Gigabit Ethernet PCIe NIC

The 2.5 GbE mod board 2.5 GbE mod board installed in NanoPi R4S

What is it?

This tiny mod board can be used to add 2.5 Gigabit Ethernet to devices that have PCIe available internally. It can for example be used to replace an existing 1 Gigabit PCIe NIC in embedded devices, upgrading them to 2.5 GbE connectivity.
The board is based on the cheap and well-supported RTL8125BG PCIe 2.5 GbE Ethernet controller.

Use with the NanoPi R4S

This mod board is tiny enough to fit inside many small form factor devices. It can for example be installed inside the ARM64-based NanoPi R4S to upgrade it to 2.5 GbE.
