Adafruit Flora Wearable Ultimate GPS Module

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:

  • -165 dBm sensitivity, 10 Hz updates, 99 search channels
  • Designed for wearable use with the Flora system
  • Only 30mA current draw
  • RTC battery-compatible - sew a battery on to create an atomic-precision real time clock
  • Built-in datalogging
  • Internal patch antenna + u.FL connector for external active antenna
  • Fix status LED

The breakout is built around the MTK3333 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 30 mA during navigation.

Please note that as of July 2021, the original module we used was discontinued by the vendor. We found and are using a nearly identical version of the module - it's a little taller (4mm) but has the same functionality. The commands for querying the antenna have changed slightly so existing projects may need to update their firmware.
