Update on kit

Was it realy intended to offer 2x RPI or was it mistake?

Yeah, we are really sorry it was missed off the internal shipping form. So these have been ordered and will be sent out as soon as they come back in stock

In my opinion two RPI make sense when communication is being tested - although ADI1110 evaluation board contains STM32 MCU that can serve as one end of  the link (and there is also possibility to set a loopback for testing), RPI seems easier to use and more popular choice

Update:

The Raspberry Pi 4 will be shipped out on Tuesday. Once I have all the tracking details, I will privately message you the tracking number and shipment link.

If anyone has any questions, pop them below 

Hi all,

You should all have a message with your tracking details. 

If anyone has any questions, please let me know 

Great! Thank you very much!

I think I noticed this a bit too late, but maybe a BeaglePlay would have been a good substitute for an out-of-stock Raspberry Pi.

The BeaglePlay has on-board Single Pair Ethernet. I never managed to make use of it as I didn't have anything to connect it to at the time. It was one reason why I considered entering this design challenge, but I decided I didn't have enough free time to do it justice.

yes - this one has 10BASE-T1L PHY (but again using different connector - RJ11  ). On plus side - some interoperability testing could be done between ADI and TI chipsets, but I think this is no 2000 year when networks  using more exotic technology should be single-vendor to avoid potential problems of different implementations...

I'm sure they would work flawlessly, the BeaglePlay has a TI DP83TD510E, which is also a 802.3cg 10Base-T1L compliant PHY.

I may be somewhat distrustful - remembering interoperability problems of early FiberChannel... But Ethernet is much simpler protocol so it will probably work as you say...
