We've been running it in this configuration for 2 years with no problems.  The levels may be 3.3V but they're certainly compatible with the Arduino digital pins.

Hello world
Last week I buy dexter industries GPS shield. I tyied to run it with arduino mega adk. I can't read GPS data over serial communication. I read that on arduino mega I must change jumper from 3 to some high pin (10,11,12) but with no success. I also tryed all examples over internet but also with no result.
please help.

regards

Hello world again
after one week testing I figure this out. I put the jumper on my dexter GPS shield to 10 and change in dGPS.cpp file ports like :

#define SoftrxPin 10
#define SofttxPin 4

and everything works fine

Glad you found the change in the software.  Did you really spend a week, it looks like you just posted the first request for help an hour or two ago. 

What kind of project are you using this for?

Hi,
i make a quadcopter. I want to control the QC over the internet. On board I have arduino mega adk + GPS shield and android phone.
I write android program that control the motors over usb, send back gps data to the server and receive command from web.
I can see QC position on my laptop and can send commands like "goto <latitude, longtitude> etc.   (sorry for my bad english)

Your English is fine, no worries.

Do you have a project page or something we could share?
