Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz updates - Version 3

Product Description

This GPS module is one of the best made so far. It comes with an array of features, includings:

  • • -165 dBm sensitivity, 10 Hz updates, 66 channels
  • • 5V friendly design and only 20mA current draw
  • • Breadboard friendly + two mounting holes
  • • RTC battery-compatible
  • • Built-in datalogging
  • • PPS output on fix
  • • Internal patch antenna + u.FL connector for external active antenna
  • • Fix status LED
  • • External antenna support and Pulse-Per-Second output


The breakout is built around the MTK3339 chipset; a 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.

Best of all, we added all the extra goodies you could ever want: a ultra-low dropout 3.3V regulator so you can power it with 3.3-5VDC in, 5V level safe inputs, ENABLE pin so you can turn off the module using any microcontroller pin or switch, a footprint for optional CR1220 coin cell to keep the RTC running and allow warm starts and a tiny bright red LED. 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.

Two features that really stand out about version 3 MTK3339-based module is the external antenna functionality and the 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.
