Description: The GP-735 is a slim, ultra-high performance, easy to use GPS smart antenna receiver. With -162dBm tracking sensitivity and only 29 second cold start time, the GP735 is a tiny, yet powerful, piece of tech. The slim design makes it ideal for applications where you don’t have a lot of space to work in. Really it’s quite small.
This 56-channel GPS module, based on the uBlox 7th generation chipset, has an operating voltage of 3.3~5.5V, an antenna on board, and connects to your system via TTL serial. The 1Hz update rate is fast enough for the majority of applications (and can be increased to 10Hz if you need) so whether you’re tracking a pet or building an autonomous car, the GP-735 has you covered!
Note: We are carrying the “T” option of this module which is TTL-UART and not USB.
Note: This receiver works with 6-pin 1mm pitch JST type cables and connectors which you can find in the Recommended Products section below!
Dimensions: 35 x 8 x 6.5 mm

Yet to test its functionality but I realized this does NOT come with the JST SH Jumper 6 Wire - 1.75" cable which retail for another $2.95. I did not read carefully and simply expected a $40 dollar GPS module would come with the GPS or the weather shield. I can’t ask for free cables but why not just put it in the package and adjust the price accordingly?

We built a small beacon for our high altitude balloon flights using this unit, a PIC chip, and an XBee. The system works great below about 40,000 feet. I specifically purchased this unit because the datasheet says it works to 50,000m. Seems that it might be able to do that, but you have to reprogram the GP-735. The problem is that there is almost zero information about how to do that. We have tracked down a possible solution that we will try. If you are not going to high altitude, then this is a great product. By the way, it will run on much lower voltage than they claim. We have been able to drain our batteries all the way down to 2.5V and still get good performance.
Using it with an Arduino Uno R3, and NeoGPS, so I can parse out both GPS and Glonass satellites. System works very well.
Works perfectly fine with an unlicensed ISM tracker. Ditched the onboard GPS and added this unit to it by soldering the signal cable to the board and used the 3.3V power output on an earlier version of the device http://www.eggtimerrocketry.com/page45.php
But has a couple of imitations the larger ones don’t have. It takes about 30 seconds for the lock to occur after power up. Once locked, the module can be put into power-down mode and come back up very quickly. Maybe it remembers its previous position and can re-lock quicker? I could not write to the module at all. I don’t think that feature is supported. I used it as a real time clock with a PIC micro to control my landscape lighting and it worked well in that application compensating for DST, etc.
This was my first time playing with a GPS on a Raspberry Pi and the GP-735 made it very simple. Just connect power and a serial port (it runs on 3.3v so just direct connect it to the RPi directly) and you’ll immediately start receiving NMEA “sentences”. (A simple “cat /dev/tty0” or similar for your setup will output it to your display).
I was in my “maker space” about 4' from a basement window and this still managed to lock on to the GPS satellites so it seems pretty robust even with a built-in antenna. It’s very small and can really fit anywhere.
It does not come with the cable that plugs into the end so be sure to order that separately…I ordered two just in case.
Ordered the cable and the unit. Used my MB500 to power it up and capture and decode the serial output. Copied the lat/long values, converted them to fractional degrees, and entered them into Google maps. Once it found enough satellites and switched to mode 2 it was accurate within a meter or two - dropped the marker right on top of me. Very nice unit.
I bought this to use as a simple GPS receiver for an Arduino project. It works great for that. Just remember to buy the recommended cable. Also pay attention to the pinout diagram in the data sheet. The black wire on the JST cable is NOT pin 1, it is pin 6. That took me a while to figure out, but once I read the manual this started feeding data to the Arduino without issue. It is not the fastest GPS module I have used, taking a while to get a fix and only 1hz updates, but the signal is solid and even sitting at the window indoors, it is getting 7 sats.
