Duet2 Eth convertor for SBC?

Re: Duet2 Ethernet Network issue
Above is the original post I made about an issue with the Ethernet port on my Duet2.
I did try Bearer's suggestions but to no avail.Since July ish, I have been running Klipper on the Duet with a SBC.
I was experiencing some issues and thought I would go back to RRF firmware to see if they resolved themselves.
Reflashed the firmware on the board, connected the ethernet and could not access the webpage - 192.168.0.7. (I checked the config using the USB cable).
I know the Duet is running as the last line of the config is to turn the enclosure lights on.Sometimes it works, most of the time it does not, now.
So I am at a crossroads, Do I purchase another Ethernet module and hope or do I do the conversion to use a SBC?
Its about £25 for a new ethernet board delivered.I have the SBC that I use for Klipper, I have a spare SD card and can create a new SD card for Duet Framework.
Is there anyone in the UK making the convertor / adapter boards as my soldering skills are only suitable for basic stuff, like DB9's!
If someone is making these boards, I am very interested in purchasing one.
Regards,
Paul

You don't need a board, you can get by with just a couple of resistors ref https://forum.duet3d.com/post/163838
I used ferules to crimp wires to regular 1/4w resistor leads, and crimped vanilla dupont terminals on the the ends. Board with buffer is probably better, but the above should work for a test-see at least.
edit: this was the post i was looking for, more pictures showing the resistors: https://forum.duet3d.com/post/163005

Thanks @bearer
What is a buffer board, out of interest?
I am not up on resistors, what value will I need please?
Something to do over christmas!

The values are on schematics in the two threads linked above i believe.
I think i used 330R for the SPI and 1K for the interrupt, iirc wilriker started off with 500R. Its just to limit the current to avoid potential damage to the pi/duet.
Buffer does sort of the same, it give the duet a high impedance (low current) input to drive. Roughly, I can't say I've studied the datasheet for the part they used on the Duet3, but the goal is never the less to keep things safe with low currents.
