Tips and questions relating to the GPS modules from SFE

To All who might know,
ok I am looking at the schematic for the GPS-MINIMOD. There is the I/O section and in it it appears to be ramping up the voltage to 5VDC. In the past all of the sensors or other items I have worked with were all 3.3 volts. I realize many of the micro-controllers on sparkfun are 5v I/O but the controller I am using is a 3.3v signal. I am just wondering if I change the 3V input to a 1.8 Volt input i should get 3.6V there right or am I missing something on this circuit .
Thanks,
Terry Massey
