Description: The SparkFun GPS Logger Shield equips your Arduino with access to a GPS module, µSD memory card socket, and all of the other peripherals you’ll need to turn your Arduino into a position-tracking, speed-monitoring, altitude-observing wonder logger. The shield is based around a GP3906-TLP GPS Module – a 66-channel GPS receiver featuring a MediaTek MT3339 architecture and up to a 10Hz update rate. The GPS module will stream constant position updates over a simple TTL-level serial port, which you can then log to a µSD card and/or use for other purposes.
Everything on the shield is highly configurable: A switch allows you to select the GPS module’s UART interface between either hardware or software ports, the µSD card operates over a hardware SPI port, which should be compatible with most Arduino layouts, and extra prototyping space should allow you to add those last, few components you need to complete your project. The GPS Logger Shield’s main voltage supply is taken from the Arduino 5V header pin. This voltage is regulated down to 3.3V, which is supplied to both the GPS module and the µSD card. These two components should consume, about 30mA on average, but they may very occasionally spike to around 100mA. We also highly recommend a 12mm Coin Cell Battery, which fits into the GPS Shield’s battery holder.
Note: The shield does not come with headers installed; we recommend the Arduino Stackable Header Kit.

Easy to setup and start using, and the fact that the programs are on the website allowed me to start logging and testing.
If you want to fiddle around with the update rate for the GPS module on this shield you can do so by sending MTK NMEA commands via the UART pins for the module we have broken out on this shield. Here are a few helpful links to get you started:
Please note, you will need to change the baud rate of the module to run at a faster speed in order for the module to accept the higher update rate commands.
Standby Mode: In this Mode the receiver stops navigation and internal processor enters standby state current drain at main supply VDD is reduced to 200 μA typ.
Standby Mode is entered by sending NMEA command: $PMTK161,0*28. Host can wake up the module from Standby Mode to full Power Mode by sending any byte via host port.
The shield only draws about 7mA after the command is issued.
