It's a conversion PCB to use with an enclosure like https://www.aliexpress.com/item/32731090429.html

splitting the 22 pin SATA to a 7pin SATA (no 3d model in the render), and using USB Type-C to power it
for use in combination with an msata to sata board that doesn't provide it's own power: https://www.aliexpress.com/item/4000516963896.html

which will be used to give terra, the pixie.town beefy server an SSD upgrade :)

@f0x looks pretty good to me ^^ I had a quick look at the datasheet - seems like the pins are aligned correctly.

@adb i guess that makes sense, you wouldn't want to do such cross-over in a flat cable either

@f0x so, I just grabbed a random SATA cable and measured it. It's not cross over. Anyways, as you are designing a pin to pin adapter it doesn't matter, as long the port isn't upside down xD
