M.2 M-key 10Gbps Ethernet

[deemekee]

Hello all,

The NanoPC T4 product description lists a 10Gbps Ethernet for the M.2 NVME PCIe expansion interface. Is this interface available and what product is suggested to use for this?

Thanks in advance,

Hello

It means only that technically you could use such an adapter like on this picture and use the available PCIe lanes to connect a standard PCIe card, which could be SATA controller card, 1G or 10Gb Network card, whatever, is just a matter of available linux driver.



That's said, keep in mind that the RK3399 SoC only has 2 PCIe lanes, and although they are stated to be version PCIe v2, their speed is still limited to 250MB/s per lane (same speed as PCIe v1), a question of power consumption I think.
The maximum you could theoretically get out of it, is a little bit less than 500Mo/s (4Gbit/s).
