LimeSDR XTRX PCIe Adapter Board

Is there plan to make XTRX to M.2 adapter with at least 2 PCIe lanes and JTAG header? M.2. Type M could even support 4 PCIe lanes.
Such adapters would be very useful for Nvidia Jetsons.

Not at this point.

Would definitely be interested in one of these as well, if/when they become available!

We sent everything to Crowd Supply a little while ago and are just waiting for them to add it to the XTRX page. I’m hoping it shouldn’t be too much longer now.

Apologies for the delay. This has now been added to the LimeSDR XTRX page on Crowd Supply:

This is exactly what I was looking for.
By the way, does the PCIe bracket come with both full height and low profile?

The time it takes to receive my first XTRX and then the FEA adaptor board and then a home (suitable PC) for it will exceed 30 days. If I find that the XTRX is DOA will I have replacement or repair support from someone? It is not clear how Crowd Supply deals with this delay between receiving a product and actually applying power.

I think just full height, but @zack could confirm.

You could always contact Crowd Supply, but as board products are essentially components which are integrated into a larger system they come with a limited 3 month warranty.

Thanks for your quick reply. I have contacted Crowd Supply. However, after some thought, I will assume that I cannot count on support and accept the loss (and order a replacement) as a risk on my part for getting a project up and running.

Thanks, Andrew. This is fantastic news! I have a few questions, if you don’t mind :slight_smile:

The page mentions that U.FL-to-SMA cables need to be ordered separately, which is fair. What I am not sure about is cables to connect XTRX to the RF frontends. Am I right it’s U.FL-to-U.FL? Do we need to order it separately as well? Any special attention to the length of the cables we need to pay attention?

P.S. Thank you guys for all your work!

Yes.

Yes.

We should probably measure the optimal lengths and add these to the docs. IIRC it’s more than one length if you do want them as close as possible, without being fully custom, to the optimal length. Of course, you could just get them all the longest length and have it look a bit less neat — which in some cases can be desirable where you want to have matched loss and phase across channels.

The unfortunate thing I’ve run into is the following when attempting to checkout the board:

This item is not CE marked and cannot be shipped to your country

The location is the Nethernalds. This happens for both LimeFEA mPCIe Full and LimeFEA mPCIe Lite.

Is it a mistake on CrowdSupply side? Are there plans to make them available for the EU/NL market?

Exciting that it’s available, but unfortunately hitting same issue in the UK too.

I’m looking into this. Note also that they’ve moved it to a dedicated project page:
