Product Description
This is the ultimate GPS module for your Raspberry Pi, Arduino or other microcontroller project! 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. Includes an 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 easily add one. Comes with one fully assembled and tested module, a piece of header you can solder to it for breadboarding, and a CR1220 coin cell holder. Battery not included. Many tutorials available at Adafruit's website.
Customer reviews
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.

20 minutes (indoors) w/o, and 30 seconds (indoors) with the battery already in place.
Performs nicely.
I've had time to continue to collect various data points and program this and a NEO-6M (both in CircuitPython/Python and Arduino's C/C++. I've decided the Adafruit Ultimate GPS is decent for most beginner projects (Adafruit's goal as I've read from them....I'm certainly a huge fan!).
In Western Washington, it closely meets its' spec of being within 3 meters when I'm in a cul-de-sac without trees or buildings for 10-12 meters. I had one-time, single position under 2 meters, but this is a single data point from many. Generally, it seems to put me about 6-10 meters from where I actually am for this region.
In the Great Flat Plains of Kansas, where the only thing in sight is the edge of the Earth in all directions, it is better being within 2 meters.
Taking the same positions from my NEO-6M, the NEO-6M just puts me spot on (<1m) with every data point in Kansas and within 2-3 meter's from some of the difficult places in Western Washington.
Having spent several hours programming both, I think the CircuitPython makes the Ultimate GPS a super product to get going. There might be better accurate data from this device as NMEA sentence it pulls data from, the GPS position is slightly different than at least one other sentence. This might be why the NEO-6M presents better, the CircuitPython pulls the information from a different NMEA sentence on the NEO-6M. My to-do list is to compare the sentence information from the same chip.
Original Review:
This took a couple hours to get setup using CircuitPython on a Feather M0 Basic.
It doesn't pick any signal up inside (unlike NEO-6M I also purchased). Once outside, it took a while to pick up signal, but was extremely stable in the location values it produced (where as the NEO-6M picked up immediately, although its' values had some flutter to them).
I'm looking forward to using both.
Some tips if you are going to use this on an Arduino:
- Baud rate is 9600
- You really only need to hook up the Tx pin to the Arduino, RPi or PC. (I don't know what commands you can send to it anyway)
- Use the "TinyGps" library in your project [...] to parse the NMEA strings from this GPS.
- No extra serial port? No problem! Use the "SoftwareSerial" library that is part of the Arduino IDE ... with that you can assign any of the Arduino pins to be an Rx/Tx pair.
- I soldered header pins to the bottom of the board so that the GPS antenna can be free and clear of any wires.
5 stars because it does the job!
Reviewed in the United States on June 21, 2020
The manufacturer's website has a really good set of documentation for both Pi and Arduino connections, and I got mine online in a minimal amount of time via a breadboard.
On warning (not this components fault at all); make sure you get the right pigtail to connect it to an external antenna. Adafruit has the right one listed, and you can find it here on Amazon too.

Je m'en suis servi pour créer une géobox. Le module était sous une planche de bois de 8mm et je n'ai pas eu besoin d'y ajouter une antenne extérieure. Par contre lorsque la ciel était très nuageux, le signal pouvait mettre quelques minutes à être récupéré.
Je recommande chaudement les tutoriels d'Adafruit qui sont complets !
Zeigt einen falschen Adapter!
Dieser hat einen männlichen SMA-Stecker, ebenso wie die dort vorgeschlagene Antenne, allerdings diesen ohne Verschraubungsmutter wie der männliche Stecker der Antenne... daher funktioniert auch ein üblicher Weiblich-Weiblich Adapter dazwischen nicht.
Ein korrekter Adapter wäre dieser hier, kostet mit 2,60€ auch weniger.

Zum Breakout Board:
Leider wird nur GPS (also das amerikanische) unterstützt, keine der neueren Technologien.
Hier wäre schon lange ein Nachbessern seitens Adafruit nötig mit Wechsel auf den MT3333 Chip, statt des hier verwendeten MT3339. Der kann dann auch GLONASS, Galileo und Beidou und erreicht damit eine deutlich höhere Verfügbarkeit sowie eine bessere Genauigkeit. Gibts als Breakoutboard für wenig Geld, dann auch direkt mit SMA-Anschluss ...
Ansonsten klappt alles, wie es soll.
Mit einer Google-Suche nach "GPS PMTK_Protocol" finden sich übrigens die möglichen Befehle, die man an den Chip zur Konfiguration senden kann. Die Version von Adafruit ist dabei aber wohl nicht vollständig, eine andere Quelle also ggf. zu bevorzugen.
