|This is another in the series documenting my setup of a new home server with the Linksprite pcDuino3 Nano. A listing for the entire series can be found here. More information on the pcDuino3 Nano can be found at Linksprite’s website and the pcDuino website.|
One of the things that drew me to the pcDuino3 Nano as a replacement for my home NAS system was the ability to connect a SATA disk to it. The pcDuino3 and pcDuino3 Nano both have a SATA host port and a 5v power connector. The 5v power connector limits you to 2.5” SATA drives.
My original plan was to use a SATA dock to house and power the drive. However, this didn’t work out as the pcDuino3 Nano has a SATA host port which is a different connector than an eSATA port. This left me with a problem as I was using a 3.5” SATA drive which requires 12v and 5v and the pcDuino3 Nano only supplies 5v. I overcame this problem by using a cable with a SATA power connector on one end and a 4 pin molex connector on the other. This allows a 3.5” SATA drive to be powered from an ATX power supply or anything with a 4 pin molex connector with 12v and 5v.
In my case I had a power adapter that supplied both voltages and by cutting off the original power connector and replacing it with a 4 pin molex male connector I was able to supply power to the disk drive. While I was at it I cut off a USB micro b connector from a wall wart and connected that to the 5v lead to power the pcDuino3 Nano.
As shown in the picture below I used an old external USB drive enclosure for the drive.
After checking all the connections I plugged in the power adapter and booted the pcDuino3 Nano.
