SATA Cable Connection with OMAP-L138 LCDK

Other Parts Discussed in Thread: OMAP-L138

Hello,

I'd like to communicate SSD through SATA. Usual SSD has 22-pin SATA connector.

However, there is only 7-pin SATA Conncetor in an OMAP-L138 LCDK.

If I connect SSD and LCDK board with 7pin to 22pin SATA Cable, do I share a power from provided 5V 3A adapter or use external adapter? If not, am I have to use a SMPS to share the power both SSD and LCDK?

As shown in first image, there are three different power, 3.3 V,  5 V, and 12 V. If I use properly, am I have to connect all?

Finally, I found 7 pin to 22 pin SATA cable below.

Is it OK to Communicate?

Thank you. :)
