Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz 

Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz  info

Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz is built around the MTK3339 chipset, a high-quality GPS module that can track up to 22 satellites on 66 channels, has an excellent high-sensitivity receiver (-165 dB tracking!), and a built in antenna. It can do up to 10 location updates a second for high speed, high sensitivity logging or tracking. Power usage is incredibly low, only 20 mA during navigation.

Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz also has a ultra-low dropout 3.3V regulator so you can power it with 3.3-5VDC in, 5V level safe inputs, ENABLE pin so you can turn off the module using any microcontroller pin or switch.

Two features that really stand out about Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz is the external antenna functionality and the built in data-logging capability. The module has a standard ceramic patch antenna that gives it -165 dB sensitivity, but when you want to have a bigger antenna, you can snap on any 3V active GPS antenna via the uFL connector. The module will automatically detect the active antenna and switch over.

The other cool feature of the new Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz is the built in data logging ability. Since there is a microcontroller inside the module, with some empty FLASH memory, the newest firmware now allows sending commands to do internal logging to that FLASH. The only thing is that you do need to have a microcontroller send the "Start Logging" command. However, after that message is sent, the microcontroller can go to sleep and does not need to wake up to talk to the GPS anymore to reduce power consumption. The time, date, longitude, latitude, and height is logged every 15 seconds and only when there is a fix. The internal FLASH can store about 16 hours of data, it will automatically append data so you don't have to worry about accidentally losing data if power is lost..
