Brand new and better than ever, we've replaced our Adafruit GPS shield kit with this assembled shield that comes with an Ultimate GPS module. This GPS shield works great with either UNO or Leonardo Arduinos and is designed to log data to an SD card. Or you can leave the SD card out and use the GPS for a geocaching project, or maybe a music player that changes tunes depending on where you are in the city.

Plug-and-Play Compatible Boards
The Ultimate GPS Logger Shield is tested and fully compatible with the following boards:- Arduino Uno (all revisions)
- Arduino Duemilanove and Diecimila w/ATmega328 chip
- Adafruit Menta (remove from tin for GPS antenna to work)
Incompatible or Partially-Compatible Boards
This shield may work with other boards with some additional steps:Arduino Leonardo
GPS:- Use 'Soft Serial' switch setting.
- Use the Adafruit SD library, specifying pin 10 for chip select, 11 for MOSI, 12 for MISO and 13 for SCK.
- Edit the file utility/Sd2Card.h in the default Arduino SD library, adding the line "#define SOFTWARE_SPI" (not MEGA_SOFT_SPI) at the top.
- Add jumper wires from pin 11 on the shield to ICSP pin 4 on the board (on the 6-pin header), pin 12 to ICSP-1 and pin 13 to ICSP-3, then use the standard library in its default state (no SOFTWARE_SPI). This is difficult due to the shield obscuring the ICSP header and is not much recommended.
Arduino Mega (all variants)
GPS:- Use 'Soft Serial' switch setting.
- Jumper from pin 8 on the shield to RX1 on the Mega
- Jumper from pin 7 on the shield to TX1 on the Mega
- In your code, don't use SoftwareSerial. Instead, define mySerial as Serial1:
//SoftwareSerial mySerial(8, 7); #define mySerial Serial1 Adafruit_GPS GPS(&mySerial);
For the SD card, the following may be tried, in decreasing order of recommendation:
Arduino Diecimila w/ATmega168 chip, Arduino NG or older
Does not work; insufficient RAM and flash program space.
- Use the Adafruit SD library, specifying pin 10 for chip select, 11 for MOSI, 12 for MISO and 13 for SCK.
- Edit the file utility/Sd2Card.h in the default Arduino SD library, changing line 42 to read "#define MEGA_SOFT_SPI 1" (default is 0).
Arduino Due
Follow instructions for Arduino Mega-
Use "Due" versions of example sketches
Arduino Diecimila w/ATmega168 chip, Arduino NG or older
Does not work; insufficient RAM and flash program space.
Pin and Address Reference
The shield uses the following pins:- +5V
- GND
- Digital pins 10-13 (Card Select, MOSI, MISO, SCK, respectively)
- Digital pins 0 (RX) and 1 (TX) when using 'Direct' switch setting
- Digital pins 7 (RX) and 8 (TX) when using 'Soft Serial' setting
Untested Boards and Other Notes
- Arduino Mega 1280: compatibility should be similar to the Mega 2560; use 'Direct' switch setting for GPS, and library changes for the SD card.
