Remora - ethernet NVEM / EC300 / EC500 cnc board

When you say the EC500 is a nicer board are you referring to the connections/layout or does it have functions that the NVEM doesn't? I see it has a higher pulse rate written on it, I understand that probably doesn't matter with how we are using it here. The NVEM is slightly cheaper but if it performs better then I'll go with the EC500.

The EC500 has 24V IO and used an STM32F407 at 168Mhz vs an STM32F207. Has a little more IO as well.

Is it showing an actual tracking event or does it just say shipped with no details

It's looking like EC500's are as rare as hens teeth now, so much so they are not even listed by Digital Dream. There is a new EC300 out.

 

A few kind people have dropped a few dollars here and there in my Paypal account so I've just ordered a 3 axis verson. It looks to be a cross between the NVEM and the EC500 looking at the layout. It will be interesting to see which STM32 it is using.

No affiliation, but this is where I found this "newest upgraded version"  www.aliexpress.com/item/1005004271315158...000028585003606%21sh

There still seems to be EC500's on aliexpress, I sorta had already ordered the NVEM and a mate was going to get the EC500 so we could compare them. He hasn't actually ordered any yet but they do seem to be there.

As far as I know the EC300 is running iMX RT1052 which is Cortex-M7 @ 600 MHz.... apparently. www.embeddedartists.com/products/imx-rt1052-oem/

This is probably more useful than the last link.
