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 the latest of our Ultimate GPS modules, a small, super-thin, low power GPS module with built in data-logging capability! This module's easy to use, but extremely powerful:

Product Description

Features

  • -165 dBm sensitivity, 10 Hz updates, 66 channels
  • Designed for wearable use with the Flora system
  • Only 20mA current draw
  • RTC battery-compatible - sew a battery on to create a atomic-precision real time clock
  • Built-in datalogging
  • >25Km altitude
  • 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.

The module is kept small and simple, we have 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, we also provide the FIX signal out on a pin so you can put an external LED on.

Comes with one fully assembled and tested module. If you'd like to back up the RTC for faster fix-recovery, pick up a sewable CR2032 holder & CR2032 battery and sew it so the + side connects to the VBAT pad and the - side connects to ground.
