Hi,

I am starting in GPS, but I have some dudes. I have a circuit that work with 5V and it has a PIC16 and a program to decode NMEA but I want to buy a Started Kit but I don`t know if I use a SmartAtenna F02 or Lassen SQ. The problem is that SmartAntenna works with 5V but is very expesive. Trimble es cheaper but works with 3.3V. My question is, Do I need a special interface to connect the Lassen SQ to PIC16 even itīs working to 5V?

Finally, Do I need a backup power to conserv NMEA protocol as default?

Thanks.
