em-408 GPS Module...

[freedom]

Hi I bought the EM 408 module lat year and have now bought an Adafruit GPSShield v1.1, is there any way to wire this up ??
Don't mind doing it myself, but the board only comes with EM 406 + EB 85 connections…
Why no EM 408 ??

What can I do ?

The tutorial is applicable to any module that has Tx, Rx, VCC and Gnd connections. http://www.ladyada.net/make/gpsshield/wiring.html
Check the 408 specs to find the pinouts: http://www.usglobalsat.com/store/download/47/em408_ug.pdf

Thank you so much, that is wonderful just what I need.
Is it also possible to stck on top of this unit ?
by getting the larger pins with sockets on the top ?

That you will have to determine by experimentation. I don't have a 408 module here to check.

Thanks One thing the tutorial shows VCC but the module has both a PWR and and on/ off input… which one do I connect to which ?

I am getting an error.

What code are you trying to use?

This

with arduino 1.0 so no new serial just the in built.

Thanks.

Post the full text of the sketch you are using. The compiler is telling you that it can't find your setup and loop functions.

That code compiles with no errors on 1.0 here.

how can I get a clean installation of the arduino software ?

[adafruit_support_bill]

Right from the Arduino site is the best place: http://arduino.cc/en/Main/Software
Where did you get the IDE you are using?

yes from there

Well try a fresh download. I don't see why you should be getting those errors with that source code.
