Use GPS positioning with your TinyDuino! This TinyShield is based on the Telit JF2 GPS Module, which uses the popular SiRFstar IV chipset. This module is configured by default to output GPS strings in the NMEA format at a 1Hz update rate (this can be changed to a 5HZ updated with a NMEA command).
This TinyShield includes an external passive GPS antenna on with U.FL connector for great outdoor performance. This TinyShield also includes level shifters and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V.

TinyDuino Power Requirements
Upon power up, the GPS takes approximately 3 seconds to stabilize before it can be put into active mode. To wake up the module, a low-to-high pulse is needed on the ON-OFF pin of the module, which is connected to the Arduino A3 pin. After waking, the module will start to stream out NMEA data every 1 second on the UART. The system can also be put back into hibernate mode with a pulse on the ON-OFF pin again. The example code shows how to handle the wake up properly.
