U.2 Backplane owners - pics?

Bit of a long shot, but if anyone has an Icydock U.2 or NVMe compatible U.2 backplane and a good camera sitting around; would you be able to send a few close up pictured of the pcb?

Specifically, I’m trying to determine, what kind of power circuits and switching are required for NVMe drives.

I’m trying to design a open source backplane to support my Gen3 NVMe U.2 drives which I can not only use myself, but can serve as a template for a backplane in any chassis. Right now, there are almost no reference designs for pro/homelab-grade SATA backplanes (support hotswap, staggered spinup, led, etc…), and absolutely none for U.2 SAS & NVMe.

On the SATA side, Arnar Ingason just posted an amazing job of reverse engineering and redesigning the power circuits as part of redesigning the backplane for his Terramaster to simultaniously support hotswap SATA drives and an NVMe drive from the same PCIe finger. (GitHub - arnarg/f3_backplane: Backplane PCB for Terramaster F2-221, adding NVMe SSD) Thanks to his work, I know what to look for on the power circuits.

Did you have any luck? Are you putting a switch on board? (PCI Express switch)

We have some Supermicro 1U SFF U.2 Backplanes, would that work?

Multi layered PCBs if I remeber, so its maybe tough to see.

Let me know

I’ve got some varieties laying around. I’ll take a few pictures when I can. If I forget feel free to poke me.
