Key Features:

For those who want to integrate our awesome Ultimate GPS module into their own projects, we now have the raw sub-module available. Don't be fooled by it's small size, this is a very sensitive, high quality GPS module with all the extras you could want and more at under 6 grams!

This module is built around the MTK3339 chipset, a no-nonsense, 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.

Two features that really stand out about version 3 MTK3339-based module is the external antenna functionality and the 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 attach an active antenna to the ANT pad. The module will automatically detect the active antenna and switch over!
