Description

This version of the Ultimate GPS is even MORE Ultimate, with support for more GPS-like networks such as GLONASS, for even more coverage worldwide. It uses a slightly taller module than our classic Ultimate GPS, and uses a little more power. Otherwise its almost identical in functionality:

-165 dBm sensitivity, 10 Hz updates, 99 channels
GPS + GLONASS support
5V friendly design and only 30mA 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

Compared to the 'classic' MTK3339 chipset firmware, the commands for querying the antenna have changed slightly so existing projects may need to update their firmware. Check the datasheet below for the new antenna query commands. Also, NMEA sentences will start with $GN instead of $GP when both GPS and GLONASS are available.

The breakout is built around the MTK3333 chipset, a no-nonsense, high-quality GNSS module that can track up to 33 satellites on 99 channels, has an excellent high-sensitivity receiver (-165 dBm 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 ~29 mA during navigation.

Best of all, we added all the extra goodies you could ever want: 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.
