can this GPS be powered using 5v? In the specs, it says that it operates with voltages between 3.5-5.5v, but just wanted to confirm this.
Well, I can confirm that the two in the links provided are 3.3V; See attachment.
But, one should never assume with these inexpensive off-shore products. If you order a 6M you will get a 6M because they want more for the 7M, but the U-blox module is 3.3V and the regulator is on the breakout board. This is where things get iffy ... breakout boards come and go and there are lots of theories as to why this happens, but a common one is that the breakouts are produced 'off-shift' during a non-inventory run. My personal experience has been very good, but please do not assume and always double-check your board to ensure the regulator is physically on the board!
If you absolutely must have things the way a picture on eBay looks, it is best not to use eBay - rather, go to Sparkfun or Adafruit or Newark or Jameco or one of the power-web sellers.
