Hello everyone,
congratulations for the forum, I found much useful information.
That said, I wanted to seek help for my project.
I have to directly connect a GPS module, for example, the EM-408
( http://www.sparkfun.com/commerce/produc … ts_id=8234 )
with the XBee module via “XBee Explorer regulated”
( http://www.sparkfun.com/commerce/produc … ts_id=9132 )
using rechargeable battery
( http://www.sparkfun.com/commerce/produc … cts_id=339 )
I need this to transmit GPS data via an XBee, in a fixed position in the open field.
I hope someone can help me, I am newbie to using these components.
Thanks to all
PS: I do not speak English well, I hope that everything I wrote is understandable 
What you want to do is posible, and actually can be implemented very easily…
I hope you know that the Xplorer is just a break out board/regulator for the Xbee and doesn’t include an Xbee… 
I recomend you read about serial comunication in MCU’s, the Non-API mode of the xbee (plain serial) and the info sent by the GPS (NMEA sentences or the protocol in wich the one you’ll by works with)… I would recommend the GPS LS20031 available from SF.
I’m sorry to inform you that is very unlikely that someone will read this and write all the code and give you the schematic of the circuit you need… you’re gonna have to do some hard work!
After you do some research you could come back and ask some specific questions…
Regarding your setup… you’re gonna need 2 XBee’s (series 1 or 2… series 1 have less “mesh” features and therefore easier, but I don’t think you need that anyways)… the GPS, the Xplorer regulated, a Xplorer USB if you want to interface to a PC, a battery, a battery charger, a 3,3V regulator if you don’t want to use the one integrated on the Xplorer regulated for the GPS…
I think that’s it! Happy researching!
