I don't know what revision sysmocom has, I previously purchased from them and it was revision A (but this was before I opened the GitHub issue). You could message them on Twitter to ask.A big shout out to @tsys and @hmartin for spending time and effort into this topic.
I would like to purchase 2 adapters for HPE 533FLR-T 2-Port 10GbE PCI-Express x8 Network adapter cards (RJ45 ports).
Ideally I want the adapter to be Plug and Play - no soldering etc.
Where may I buy those? I am located in Germany.
I found this, but do not know the revision - A, B? C most like not.

No, only Rev C. Broadcom-based cards require A10 and A11 to be pulled to 3.3V, which Rev B does not do.I am curious: wasn't revision B to work out of the box with the 533FLR-T?
Thank you for the clarification, I got it now.It should be easy to modify Rev B cards by adding a wire to A10/A11, but you asked about finished adapters and for that I have only modified Rev A.
I don't believe NBASE-T is supported by the cards, the NBASE-T standard is too recent (802.3bz-2016, versus the cards which are from 2014).I do have a new question:
Is it possible to set up the NIC with 2,5 or 5 GBit mixed mode?
the NIC HP FlexFabric 10Gb 2-port 533FLR-T does only offer 1 or 10 GBit speed, no 2,5 or 5 GBit inbetween in Windows 10. TrueNAS only shows a 1 GBit connection as of yet since I do not have another 10 GBit card atm.
Really? I have not had any issues in fitting the cards into the PCI slot opening in the chassis. They cannot mount like a normal PCI card because they are missing the L-bend, but I didn't have to modify the case. Can you provide some photos of what you mean?the adapter is working - cutting the rear of the PC case was required, the adapter and NIC do not align.
Hi Martin,If anyone in the EU is looking to purchase unassembled Rev B adapters, drop me a PM. I have around 20 available which I'm selling at cost (approx. 3€/adapter + shipping). I cannot assemble them for you, you will need to solder it yourself.
No, sorry, I sold them all. Updated my post to reflect this.Hi Martin,
do you still have adapters? I'd take 5 of them if possible.
Cheers,

why not get Mellanox CX3+ and a DAC? Cheaper and faster.This is a really interesting thread and I'm glad I found it before buying some HP 561FLR-Ts.
Plan is to use them, channeled bonded for direct attachment between two desktop machines that will both be dealing with multicam 1080p video editing and transcoding. Consolidate most of the SSD storage onto one machine, Samba share, etc. Current NAS nowhere near fast enough to edit directly from.
Understand that 561FLR-T are PCIe Gen 2. How would they perform in Gen 1 slot with read workloads as opposed to theoretical bandwidth limits etc?
