Hi,
I bought a XTRX board and PCIe adapter a few years ago and would like to spend some time to play with it.
Is the schematics and/or FPGA pinout available for this board somewhere?
I tried the Fairwaves web site, but the contact form does not seem to work.
BTW I know there is a new version of the board available, but I was hoping to use the old board to develop some Verilog RTL.

I found it:

Or is this the new xtrx since it’s based upon a xc7a50t and not a xc7a35t? It’s a bit problematic searching for two different projects with the same name.

That repo is for Fairwaves XTRX, but note that they had hardware variants with different size FPGAs.

To make the information more complete in this topic:
Fairwaves XTRX up to hardware revision 4 had the smaller sized FPGA. The Fairwaves XTRX hardware revision 5 was the last one they had build and this had the bigger sized FPGA. The LimeSDR XTRX also use the same sized FPGA like Fairwaves XTRX revision 5. That is why LimeSDR nicely to the community added firmware support for the same sized FPGA and board Fairwaves XTRX revision 5.
