Version 3 comes with the latest module which has external antenna support and Pulse-Per-Second output

Adafruit believe this is the Ultimate GPS module, so they named it that. It's got everything you want and more:

  • -165 dBm sensitivity, 10 Hz updates, 66 channels
  • 5V friendly design and only 20mA current draw
  • Breadboard friendly + two mounting holes
  • RTC battery-compatible
  • Built-in datalogging
  • PPS output on fix
  • We have received reports that it works up to 32Km altitude (the GPS theoretically does not have a limit until 40Km)
  • Internal patch antenna + u.FL connector for external active antenna
  • Fix status LED

The breakout 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 snap on any 3V active GPS antenna via the uFL connector. The module will automatically detect the active antenna and switch over! Most GPS antennas use a SMA connector, so you may need an adapter uFL to SMA.

Adafruit have a nice library for GPS usage (called LOCUS). A full tutorial is also available.
