 Bigger Bigger  Smaller Smaller  Reset Reset

Hey all!

I recently received this module in the mail:
http://dx.com/p/gy-neo6mv2-flight-controller-gps-module-blue-232595

I have looked everywhere for information on how to wire and program this GPS module, all to no avail. Can anyone point me towards some info on this module? My setup is a Uno Rev 3 and the Ublox NEO6MV2 GPS module. I am still new to this world of the Arduino, so a "For Dummies" setup would go a long way!!

First three connections are straightforward:
* Arduino 3.3V -> GPS VCC
* Arduino GND -> GPS GND
* Arduino RX -> GPS TX
Connecting the Arduino TX line to the RX line of the GPS module is complicated by the fact that the GPS runs at 3.3V and the Arduino runs at 5V. This voltage divider brings those Arduino signals down to ~3.3V.
*Arduino TX -> 10K resistor -> Arduino GND
*Arduino TX -> 4.7K resistor -> GPS RX

Tutorial for the software side of things: https://www.sparkfun.com/tutorials/173. Remember that the baud rate of your module is default at 9600 unlike the 115200 in the tutorial.

First runs of GPS modules take a long time. You might need to step outside to get a lock, and might find yourself waiting a few minutes as well.

Hi, sorry, if I can correct you, you have not correctly indicated the connection.
To have a correct voltage divider, you have to connect:
*Arduino TX -> 4.7K resistor -> GPS RX
*GPS RX -> 10K resistor -> Arduino/GPS GND

Have fun smiley-wink

I made a little tutorial how  to use the NEO6MV2 with Arduino Uno.

Hmm...

I gave it 5v from mine and hooked it up without resistors... worked fine for me.
