Adafruit Ultimate GPS Module with USB

Adafruit Ultimate GPS Module with USB is built around the MTK3339 high-quality GPS module that tracks up to 22x satellites on 66x channels. This 5V module features built-in data logging, a low 20mA current draw during navigation, an internal patch antenna, and a u.FL connector for the external active antenna. A high-sensitivity receiver provides -165dB tracking with up to 10x location updates a second for high-speed, high-sensitivity logging or tracking.
