A Pass-through software that makes it possible to comunicate diretly with the GPS module

Browse source 
Use this software if you need to connect directly to the GPS module for example from the u-center software.
This software does NOT program the GPS module to output RF so remember to restore the original firmware again after you are done.

/*Software for Zachtek "GPS Referenced RF Generator"
Arduino software that just passes serial data between the Arduino Serial port and the Ublox Neo-6 onboard GPS module.
This can be useful in trouble shooting scenarias, expriments etc but the main use would be to be able to controll the GPS module from the PC based U-Center software.
Arduino pin A0 is output - Voltage Regulator Enable
pin 2 and 3 is Sofware serial port to GPS module
pin 4 is output - connected to the IDC connector
pin 5 is output - Yellow LED indicator
For Arduino Pro Mini 8MHz
