This is my very first Arduino project. I want to learn about GPS navigation by exploring the NMEA protocol!
Therefore, I bought a WeeBee GPS module. After reading the datasheet, I have two questions:
The official Arduino website states
Note: if you are using an Arduino Uno, keep in mind that you can't use the GPS module at the same time as your computer is connected on the USB port.
But I you go to the end of his tutorial, you will see he can transmit the GPS data to his computer. I don't understand why it would not be possible...
The GPS module datasheet (download link here) states that the maximum voltage is 5V. But it also states
serial connections are 3.3V CMOS Logic Levels
Suitable decoupling must be provided by external decoupling circuitry.
So, does it mean I need a logic level converter to prevent damage to the GPS module?
