Datasheet

The Wing 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.

The MTK3339-based module has external antenna functionality. 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 SMA connectors so you may want to pick up one of our uFL to SMA adapters. (http://adafru.it/851)
