I just got a second hand Nano from ebay and it didn't came with any cable or instruction, just the nano and antennas. (so lame I know, but it came in a bundle with something else I needed)
I haven't even power it yet, but from google pictures I saw the Y cable should be like female USB A to 2x male USB A,.
I start looking on local market but haven't found any on my country yet, and Amazon don't ship them outside US either. I will figure out where to buy it, but in the meantime, what do you thing on building it for start using the Nano ?
This video shows 1 USB extension split and joined again by colors, and then just add an extra USB male cable adding only the powers color cables.
Thoughts?
