NETMF board with RJ45 Ethernet

Hi, I am looking for a replacement/feel alike for the (sadly) long time ago discontinued Mountaineer Ethernet boards (https://www.ghielectronics.com/catalog/product/385). It's OK if it's not Gadgeteer (although I do like the connectors) but I would really like to be able to keep using my NETMF code base/base library knowlegde/ease of use.

Am I missing something, or is there nothing available (aside from the development boards which are too large/costly) that is NETMF and has onboard Ethernet?

On the G30 TH page, it says it's not able to do networking, but on the G30 develop page, there seems to be something that looks like a RJ45 connector. If so, what are the minimum requirements/parts list in order to do reliable networking using G30 TH or G80 TH?

G30 has no networking
G80 has SPI networking (so you need to use ENC28J60 module)
G120E has Ethernet PHY (edited to correct)

I'd personally go to G120E.

edited my post for correctness, thanks for the QC job!

GHI, the table with tick marks against features in https://www.ghielectronics.com/catalog/netmf is misleading in the G120/G120E situation Smiley It's not until you go into a G120 or G120E that the "the difference" text is clear about the PHY

I am looking for single-board solution, at least for the microcontroller and the Ethernet RJ45 port. I will add some peripherals on a use-case basis.

So, is it planned to have a through-hole version (or anything else less "soldering-fiddly" than SoM) of the G120E chipset that features an Ethernet/RJ45 connector built-on?

I found the G120 SoM is very nice for hand-soldering Smiley.

sounds like time for a community board with G120E and Ethernet Smiley

Well, I was expecting that GHI wouldn't offer a Cobra IV.Net given the Cobra II.Net went on the endangered list some time ago and Cobra III is netless. But I agree Smiley

Gus can we have one please? Pretty please?

@glx - would you care to share a picture of that? From what I can see on the store picture, the contacts look quite cozy... did you also connect it to a RJ45?

I just used the G120 (without "E", because I use WiFi) on a custom PCB (there's a picture below) it's completely hand-soldered (except the USB-jacks, they are not nice to solder, they were done with a cheap hot-air (very cheap, so I didn't want so solder anything else with it)) Smiley. I had a G400 for testing, there was the only needet thing a RJ45-Jack with magnetics) no other external components for Ethernet Smiley.
