Odroid-H2 Net Card

The ODROID H2 Net card brings 4 additional 2.5 GbE Ethernet ports for an incredible low price. It is compatible with the H2, H2 rev. B and H2+. Using a H2+ you end up with a total of 6 x 2.5 GbE Ethernet ports. With the H2 and H2 rev. B you get 2 x 1 GbE and 4 x 2.5 GbE Ethernet ports.

The ODROID H2/H2+ with the ODROID H2 Net card brings new capabilities and applications. Examples (non-exhaustive list):

• Implementing a DIY router or gateway for up to 5 (H2+) clients at 2.5 GbE speed on each port.
• Setup a DIY server, e.g. a NAS, for up to 6 (H2+) clients at 2.5 GbE speed on each port.
• Brings 2.5 GbE Ethernet connectivity to the H2 and H2 rev. B boards making them able to talk at full speed (usually 2.35 Gbits/sec) with H2+ boards.

Performance

Note: In the network throughput, those two charts show slightly different numbers so it looks like the upload speed is slower than the download speed. But it is not, because the logging tool which I used shows the actual throughput in E+06 formula, like “2.30e+06” rather than using the Mbps unit. In fact, all the NICs performed at 2.34~2.36 Gbits in both directions.

Warning: Have to flash GLK-ESF BIOS to use H2 Net Card properly.
