DESCRIPTION

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

Voltage: 3.0V - 5.5V
Current:

37mA (Full Power Tracking)
10mA (Low Power Tracking, 1Hz)
14uA (Hibernate Mode)
Due to the current requirements, this board cannot be run using the TinyDuino coin cell option

Pins Used

A0 - GPS_RX: Software UART Transmit from the TinyDuino to the GPS Module.
A1 - GPS_TX: Software UART Receive to the TinyDuino from the GPS Module.
A2 - SYS_ON: This signal is an output the GPS module to indicate if the module is in an active mode (the signal is a logic-high) or in hibernate mode (the signal is a logic-low). By Default this signal is connected between the GPS module and the A2 signal using R7, which is a 0 ohm resistor. This resistor can be removed if this signal is not needed to free up A2 for other uses.
A3 - ON_OFF: This signal is an input into the GPS module, and is used to transition between hibernate and active modes. Transitions between states are made with a low to high pulse on this signal (minimum time of 100uS).

Dimensions

20mm x 20mm (.787 inches x .787 inches).
Max Height (from lower bottom TinyShield Connector to upper top TinyShield Connector): 5.11mm (0.201 inches)
Antenna: 10mm x 10mm x 7mm (.394 inches x .394 inches x .276 inches). 40mm (1.57 inches) cable with U.FL connector
Weight: Board: 1.65 grams (.06 ounces) Antenna: 2.60 grams (0.09 ounces)

NOTES

Previous versions (Rev 3 and earlier) of this board shipped with an integrated chip antenna and the board size was 20mm x 28mm. The integrated GPS antenna is not as sensitive as larger GPS antennas. This antenna will not pick up GPS signals indoors and will only work well outdoors. For best results, keep all metal aware from the antenna and make sure it is used in an outdoor environment.
Note: A number of the revision 5 TinyShields have modules configured to run at 4800 baud instead of 9600 baud. So if during testing the module does not seem to work at 9600, try it at 4800 baud.

Arrived quickly and works great.

Got it working

Got it working Coupla years ago
Have new sub-orbital use for it and will
be bring it up again if I can

Completely overpriced and didn't work anyway!
