Adafruit Ultimate GPS Module Breakout - 66 Channel w/ 10Hz Updates
- Product ID: 169
- MPN: ADA746
Adafruit's Ultimate GPS module breakout board, as name suggests is Ultimate. It has loads of features that makes it more useful than anything else in the market. The features of the modules include:
- -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
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.
Moreover there is an ultra low dropout 3.3V regulator which allows 3.3V-5V input, 5V level safe inputs, optional coin-cell battery footprint 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.For more info about the awesomeness of this module refer to Adafruit's product page.
