Description

This module is the best way to add a GPS to your wearable project. It’s part of the Adafruit Flora series of wearable electronics, designed specifically for use with the Flora motherboard. Installed on the PCB is a small, super-thin, low power GPS module with built in data-logging capability! While these are designed for wearable applications, their small size does make them quite useful for conventional projects as well!

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.

The module is kept small and simple, there is a ferrite bead, filter capacitor and red fix LED on board. The LED blinks at about 1Hz while it’s searching for satellites and blinks once every 15 seconds when a fix is found to conserve power. If you want to have an LED on all the time, there is also a FIX signal out on a pin so you can put an external LED on.

Two features that really stand out about the MTK3339-based module 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!
