I received neo - 7m gps and the wire welds are not at all well done unfortunately .
I would like confirmation if the compass is integrated in it .
There are the six wires GND, VCC, TXD, RXD, SCL, SDA.
I see a chip L8832036 signed , could be the compass ?

Yes, that is the mag chip.  It should work fine with a revo.  Unlike the Naza ones it will take up both the main and flexi ports.  Since it doesn't have a flash memory chip it won't work with a cc3d.

The first 4 wires (gps and power) go to the main port and the last two (mag) go to the flexi port.  The wiring is in the wiki at https://librepilot.atlassian.net/wiki/display/LPDOC/GPS+setup#GPSsetup-GPSwiring and your gps is the one on the left.

Ok, thank's for information.
I suppose that flash memory chip is the missing chip U2 on the board near Neo 7M?

[hwh]

Yes, that's the one.  It doesn't matter unless you want to use it with a cc3d.  The revo and sparky2 normally (you can disable it) reconfigure the gps with the optimum settings for them every time they boot up.

For now I do not care to use it in flight , but how can I check if the GPS is working properly and receives the satellites?

In GCS you can see number of satellites and whether it gets a stable 3D lock/fix. If you're losing 3D fix, then you need to wait till it finds more sats.

I can use GCS 15.09? Connect only main port?
I remove

15.09 supports only one GPS+AuxMag unit which is OP Platinum GPSv9 (not produced anymore). It also supports Ublox protocol GPS units, but that's just GPS alone and not very useful if you indention is to use navigation.
16.09-RC1 supports external magnetometer so you can connect Ublox GPS and HMCxxxx mag, it also supports GPS+AuxMag (over I2C) and DJI GPS (unit also contains AuxMag and I recommend this one).
For 16.09-RC see https://forum.librepilot.org/index.php?topic=2266.0

To just test GPS unit alone, you can just connect main-port with 15.09 and it will show sats on Revo. Remember GPS and Mag are two different devices that both are needed for navigation, and it just happens some GPS units have Mag integrated.

I can connect the cable without perform a wizard?

[hwh]

Yes, just go to the config tab and set the settings for the port(s) you plug it into.

Thanks.
It's just power the revo through the USB cable from the PC or do I connect the battery lipo?

[hwh]

USB powers only the flight controller itself, nothing plugged into it gets powered by USB.  To power a GPS (or a receiver) you have to connect the battery.

Ok very well

You know if revo board ports are protect by connection with devices with defects? I'll explain. A device with defects can damage the revo?

[hwh]

The original project's revolution had protection on the input ports.  On the various Chinese clones the protection chips are sometimes there, sometimes not.  Even on the ones with the protection chips it's still possible to damage the revo but they make it less likely.

That said, a bad GPS is unlikely to damage the revo.  For the most part it would have to put more than 5 volts onto a revo pin and I've never seen a GPS module that had more than 5 volts on it.
