Venus GPS uart ttl level connection Arduino

Hi

I just got the Venus gps module with the sma connector. So i intend to use it with the Arduino Mega. I also have an Arduino deluminalove. So about the 3.3 volt uart… Do i need a TTL logic converter from 5volt to 3.3 volt ?

For the power supply, i ran the gps on an external dc-dc converter from 5 to 3.3volt. But i’m stuck with the connection… it’s that to go on the uart port directly ?

and i see some people having problem getting the right library to work. Any have a good working one with the Arduino…

thanks a lot

You will want to get a level shifter. Sparfun sells this one that will work for your needs:

You could get a 3.3v arduino too :lol:

This library will work just fine for you:
