Ultimate GPS Logger Shield and Leonardo

by shankar1 on Tue Mar 12, 2013 11:47 am


I am new to Arduino projects. I have a Leonardo board. The board is currently using the
1. SPI for data logging to a SD shield
2. Pins 0(RX) and 1(TX) (leonardo's UART) is used for connecting to another module for serial communication.

I would like to add a GPS module. With the Serial pins 0 and 1 already in use,
1. will I be able to connect the Ultimate GPS Logger Shield to some other digital pins?
2. Will I be able to use SoftSerial library to communicate with GPS? is there any draw back in doing so?

I am planning to have my application poll both the GPS module and the other serial communication module for data.

Yes, you can connect the GPS to any unused pins that support pin-change interrupts - see the Leonardo limitations here: http://arduino.cc/en/Reference/SoftwareSerial
