The ODROID H3 Net card brings 4 additional 2.5 GbE Ethernet ports for an incredible low price. It is compatible with the H3, and H3+. Using a H3+ you end up with a total of 6 x 2.5 GbE Ethernet ports. With the H3 you get 2 x 1 GbE and 4 x 2.5 GbE Ethernet ports.
The ODROID H3/H3+ with the ODROID H3 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 H3 board making it able to talk at full speed (usually 2.35 Gbits/sec) with H3+ boards.
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.
