I am playing around with the Sparkfun Venus GPS. I followed this tutorial to get started. In here the author states that you should
Upload the following sketch to your Arduino BEFORE making any connections. 5V from an IO pin left high on the Arduino may well kill the 3.3V output from the Tx pin on the GPS module.
However, I am using the Sparkfun bi-directional logic level converter in between the Arduino and the Venus GPS (because I'm using the 5V Arduino GSM shield stacked on top of the Arduino). In that case, would the above statement still apply?
