I have added SATA to Pogoplug Mobile V4 A01. Components that need to be installed are:
- Four coupling capacitors C5-C8 , value is 10nF , case size 0402 or 0201 (located near SATA connector). Value is not critical. My guess is anything from 3.3nF up would work.
- 0 Ohm jumper resistor at the position R206 ,case size 0402 or 0201 (located near USB connector and electrolytic cap)
I did not bother to buy a 22 pin male SATA connector. Instead I took a spare red SATA cable, cut one of the connectors off and soldered it directly to the board . Pin #1 key should be connected where the middle of 22 pin connector would be on the board.
Once you strip SATA shield off , you will see four coax lines. Solder them to respective SATA signal lines on PCB. Again, the sequence is such that the key would be in the middle of the bar of bare pads for 22pin connector.
I scraped off some solder mask next to USB connector and soldered down the shield of SATA cable there. Make sure you put some Scotch tape to protect the PCB components from shorting out.
Then I took a spare Molex to SATA power adapter, cut off Molex and 12 Volt( yellow ) wire and attached remaining 5V red wire and ground black wire to power bus of USB . 5V was fed from the fuse F2.
Next you connect a 2.5" SATA drive and you are good to go.
The drive is recognized and you can see it in the output of dmesg command.
