Hello friends
What is u- control ? Is there Shield
Or
There's a software?
Based on the following link:

Are you talking about u-center? There's a link to it in the Instructable. It's a Windows application that talks to the Neo-6M directly (no Arduino). You need a 3.3V Serial-to-USB converter to connect the Neo-6M directly to the USB port. You connect the converters RX/TX to the Neo-6M TX/RX. Step 2 shows his PL2303 converters for this, but FTDI232 or CP2102 USB to Serial converters would also work.

Thank you for your description
How is the performance of this module?
Does it always have to be connected to the computer?
Or after planning is disconnected from the computer?
I want to take this module in the car!
Whether the module only needs batteries or need Internet access?
Thank
The instructable shows two ways to use the GPS module:
-
ucenter on PC <-- USB cable --> USB/Serial Converter <-- wires --> Neo-6M
-
Arduino <-- wires --> Neo-6M
Of course, to program your Arduino, you connect it to your PC:
- PC <-- USB cable --> Arduino
The Arduino can be connected to both the PC and the GPS module at the same time. But, to use ucenter, it must be hooked up like (1). The Arduino is not connected in (1). Ucenter is a Windows application you can use to make sure your GPS works and to configure it.
To run a sketch you have written on the Arduino, use (2). The PC is not required, unless you are uploading a new sketch, like (3).
In the car, you can do either (1) or (2) or (2)+(3). You can power the PC and/or Arduino from the car battery, with the right power supplies.
Internet access is not required for (1), (2) or (2)+(3). You only need internet access to post a question here, or to get libraries and example sketches for the Arduino.
Note: the Neo-6M GPS module is a 3.3V device, while most Arduinos are 5V. The wires in (2) can damage the GPS module. Tell us which Arduino you have, and we can describe the safe connection for (2). For (1), USB/Serial converters can be either 3.3V or 5V. Be sure yours is 3.3V

Thank you dear friend:
You have to work with this module?
The strength and quality is how?
I mean Ublox NEO-6M GPS
English?
What do you mean?
english!!!
@ /dev:
there are GY-NEO-6M V2 modules available which are 3-5 V compliant:
I have one and I'm running it successfully both on a Mega and on a Due.
It has a 3.3V regulator, so it should be powered by 5V, but it does not level-shift the TX and RX lines, as you can see on this photo from the seller's listing:
The ublox documentation clearly states that 3.6V is the maximum input. Although the TX output is marginal WRT to Arduino input, a direct connection from the Arduino TX ouput applies ~4.7V to the GPS RX input. At a minimum, this pin will draw more current, decreasing battery life. At the most, it will increase the operating temperature and eventually damage the RX pin.
Rather than rely on anecdotal evidence, just add a few resistors and operate within spec, SAFELY.

P.S. That doesn't look like a real ublox GPS, so I wonder what its input spec is...
do I understand you correctly: do you mean my device is not the original ublox GPS?
which means conclusively...?
If your module just has that barcode on it, it doesn't look like a real ublox NEO-6M. It may be "compatible", but it doesn't look "genuine". Google shows a bunch of modules with the specified label, unlike yours. Instead of "PPP-GV-T-XXX", they say "NEO-6M-0-001".
It may be working fine for you, I'm just pointing out that the Electrical Specifications for your module may be different from a real module. The ebay listing just says "Power supply: 3V-5V", which makes sense, because there is a 3.3V regulator/battery charger on board. It does not say anything about the RX/TX signal levels, and they are directly connected.
If you really want to know if it's stressing your module, you could measure how much current is going into the RX pin. If it's more than a fraction of 1mA, that would tell you that the pin is sinking current, probably through the typical input protection diodes. This would mean that the input pins were not designed for a 5V logic input.
For comparison, you could use a resistor divider to scale the input voltage down to 0V-3.3V, and measure the current going into the RX pin from the divider. At 3.3V, it should be microamps. However, most people, including me, do not have the equipment for measuring currents that small. So I just use a level-shifter and call it done.

unfortunately I can't measure current.
But what a f***ing crap if they say 3-5V compliant and then the levels are not shifted accordingly!
I have one and I'm running it successfully both on a Mega and on a Due.
Many people have reported the same success. It might be ok, even though it's out-of-spec. Of course, we don't really know the spec for that module.
Do you have two resistors with values in a ratio of 5:3, or 2:1, and add to anything between 10k and 200k? Like a 47k and a 33k? You can make the divider:
Arduino TX --+
|
33k
|
+----- GPS RX
|
47k
|
GND
Do you have just one resistor between 2.2k and 22k? Between the Arduino Tx and the GPS Rx, it can limit the current to safe levels.
