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.

I purchased this product to experiment with the Raspberry Pi and GPS features. I found this product works as expected and was easy to setup and get working. Up and running on my Pi in under 10 minutes from opening package. This item can be used as a GPS data logger and one example they use is to put it on an animal for tracking. The GPS logger is limited to 15 second points.

Final use is for a Stratum 1 NTP time server for my home network.

Battery choice is the only reason I didn't give this a 5.

Pros:
- Can be used with any device that can work with USB using an TTL to USB adapter or via 3.3V TTY input including cell phones.
- Software examples and tutorials are all over the Internet and right from Adafruit's own web site.
- Complete with external antenna which is required if you are in a building. Antenna has a magnet mount.

Cons:
- Battery holder is for a battery that is harder to find. A CR2032 would have been a better choice.
- Better documentation shipped with the product explaining how the supplied header should be attached, if you want to use it.

I bought this for the pulse per second output and am happy with the results. The jitter in the one second pulse period is only a few nanoseconds and the pulse signal is very clean with good rise time. I'm using this to adjust the local oscillator on my Agilent frequency counter.

Possibly the best gps device available for hobbyist. I also own an EM-506 device which may have better reception, but its large size isn't worth it. With the ultimate gps, you have the option of using an external antenna.
