The backplane is made to be integrated in my DIY NAS server case, behind the HDD cage.
Each backplane is design for 3 HDDs powered by 2 SATA power connectors and you need 2 of them for my DIY case.
Power and data connectors are on one side and SATA headers on the other.
Here is the result :
I've seen your case on Thingiverse previously and now I'm stumbling upon your pcb here on Hackaday. You did an awesome job all around in your build. I'd like to replicate a similar PCB for my own needs so thanks for the idea.
What are the capacitors there for?
Also, the snake-like pattern of the data traces to make them the same length, is it a feature of KiCad or did you make it manually?
