Would this board be a working prebuilt ETH module perhaps?

I’m No expert, and its hard to tell just looking at a picture of the board, but it sure looks almost exactly like the schematic for the ETH module. connector pinning appears different but it has the right signals present. I bet it would work.
And then I scroll down and see a schematic. only a few slight differences.CS and RESET have 10K pull ups not present in the MBHP ETH schematic, and the MBHP ETH has an extra 100uf cap on the pin 1/2, and 100nf cap on VDDTX (bypass cap). A few resistor values are slightly different. only thing I see as a potential problem is the extra pull ups, which could be desoldered if needed, which I again am no expert and maybe they are fine to leave in…
It looks like the module is a generic 3.3V SPI module, so it should work. I can’t think of any reason why not. Those modules can be bought from Ebay for about $2.5 including ww-shipping. Think I order some to try them out.
It should work, I’m using the same kind of thing on my MBSEQ.
Have a look at this thread as it may help.

Thanks folks. I have a Core-Elec voucher to use up so I’ll just get one and see.
