I found the GPS performance of the board to be very poor with few satellites detected and frequent position loss. I switched the to powering the Vcc pin from the 5 volt Raspberry Pi pin. Performance is now excellent. Although indoors, the unit maintains an almost constant 3D position lock. Apparently, the Vcc pin needs at least 3.6 volts to regulate properly to 3.3volts needed by the internal GPS module. The 3.3 volts from the Pi is not sufficient for the on-board voltage regulator to pass the 3.3 volts through to the module. If using a Pi, power the unit from +5 volts! This does not affect the other I/O pins on the GPS board at all, as they all run at 3.3 volts.

The GPS module works immediately. The GPS fix can take time depends on the last satellite that the module he registered. After the first time, it acquires it fix very quickly.

The GPS fix can take time depends on the last satellite that the module he registered. After the first time, it acquires it fix very quickly. If the GPS is not in use for several days, it can retake time to obtain a position fix. To get a faster position fix, make sure you have an unobstructed view of the sky. (The LED blinks when the GPS have a good signal and a position fix.)

I have been unable to find one, but if you’re unable to make a sketch for it then visuino makes it incredibly easy to get it running

Yes, this is a car GPS, thicker pcb board, electroplated chip, increased resistance, LNA secondary amplifier filter, enhanced signal stability, good sensitivity

Hi there,
What is the actual display on the module after you have run 20 kilometers? We have professional technicians who will calculate the error and give a solution.
Thank you

For best reception, the pc board side of the antenna should be down and the antenna should be a high as possible in the waterproof container (hopefully not metal).

GPS relies on radio reception so the antenna has to "see" the sky as much as possible. There are larger antennas available if this one doesn’t work out well inside the enclosure.

It gives dimensions in he specs. You an also find a data sheet online.

I was able to read NMEA messages at rate of 2 messages per second using python script on my raspberry

The product mainly enhances the installation and stability of the signal, is also waterproof, and adds two installation methods, as well as a three-meter-long line for your better installation

Yes it can be used to set the pi real time clock. You have to connect it to a pi serial port and create a program on the pi to get data from the gps messages it sends. lots of info on youtiube/internet on how to do this. I had mine talking to an Arduino in 15 minutes

If your date and time are correct then you are not parsing correctly for the location.

If your date and time are not correct, you need to try outdoors for a better position to the sky to receive a signal. … If your date and time are correct then you are not parsing correctly for the location.

Once you get a signal from the satellite, you can move indoors to make adjustments to your code.

Hi there,
The link is still works. I have checked.
There is a ";" at the end of the link. It is useless, please delete it and try again. … Hi there,

yes, this GPS is installed in the vehicle interior, but it is waterproof, ABS waterproof: IP68

My antenna was quite difficult to get on so it could be a bad connection there. You could be in an area without satellites it can connect to, or possibly the library you are using for the code. Might also be unable to connect if inside a building with thick or concrete walls.

You could be in an area without satellites it can connect to, or possibly the library you are using for the code. Might also be unable to connect if inside a building with thick or concrete walls.

Good way to eliminate the code as the problem is the find one someone has written for these and just testing if it can connect with that

This chip is a clone of the U-Blox Neo-6m. U-Blox.com has lots of documentation at U-blox.com
It’s a 5 volt device. With Rx and Tx both 5v. The default Baud rate is 9600 bps which is higher that typical modules. It works with TinyGPS and Adadfruit GPS libraries once you are connected. You can use the USB micro B plug to access the chip directly The U-blox U-Center software will interface directly thru USB.
The U-center is complex and powerful but daunting. Since the device is a clone not every feature is guaranteed to work through U-Center but many useful settings do work.

Another USB direct software is VisualGPSView. (Free)

The USB connection is a different channel from the serial and may use a different baud rate.
Double check which:
-Baud rates are used
-Voltages used on each pin
-Reverse Rx Tx pins just to be sure

This info cost me a lot of pain to learn so try it out. I love this module and I am using several already. It is very sensitive and gets a fix fast.

The media could not be loaded.  This little unit is a great value. It does appear to use an authentic U-Blox chip under the metal can and white label. Most U-Center software functions seem to work just fine.

I interfaced mine to a Raspberry Pi 2 to make an NTP time server. The PPS connection allows accuracy down to a few 10s of nanoseconds. This requires configuring the Raspberry Pi to accept a PPS signal on one of the GPIO pins. I used the “GPSD” and “NTPD” packages, which interface nicely with the unit. Be sure to hook up to the TX and RX serial lines, as GPSD appears to update the time and other parameters that allow a rapid “cold” fix when first powered up.

A word on power and levels . The module on the board operates at 3.3v!!!!! However, this board has a 5v > 3.3 volt regulator that allows powering from the USB connector. The Vcc pin also connects to the regulator input.

***UPDATED*** The module can only be powered from 5v on the Vcc pin. The onboard voltage regulator does not function properly with the Vcc pin connected to 3.3v. It appears to function normally, but will be subject to very frequent dropouts of 3D lock and other erratic operation. Also. operating the board from 3.3v on the Vcc pin would subject the device providing power to 5v on its 3.3v output should the USB port be connected to a computer for programming the board. Be careful.

The TXD, RXD and PPS pins all operate with 3.3v as their logic high input/output levels!!! A read of the data sheet from the link in the listing clearly states theses interface pins are NOT 5 volt tolerant. That means if you use a device (like an Arduino) that uses 5v as its logic “high” to connect to an input on this device (RXD), you will probably damage the chip. It may work for a while, but it is stressing the chip beyond the absolute maximum ratings.

The PPS and TXD pins are outputs, so no damage results connecting these to a device expecting a 5v input, but the data will be very sensitive to noise and corrupted data on the receiving device (an Arduino, for example). It may seem to work OK, but you would do better investing in a cheap bidirectional 5v <> 3.3v level converter chip for a few dollars if you want to connect to an Arduino.

The device is perfectly matched in terms of voltage levels to a Raspberry Pi, however!

My application is timekeeping, and certainly does not involve flight control.
This module was intriguing given its low price relative to other modules.

Notes:
• MicroUSB connector makes it super quick to check operation against a 9600 baud serial port/terminal.
• Operates on 5V, and I’ve confirmed on a scope (and by use) that both the TXD and PPS output TTL levels.
• Draws ~35ma @ 5V.
• PPS is a positive-going 100ms pulse and it appears that the positive transitions mark the *next* received sentences, and seconds=00. Note that PPSs only appear when there’s an actual fix (eg. $GPRMC Status term = ‘A’) The little red LED on the breakout board seems to be wired as inverse-PPS, so solid red until a fix, then pulsing off in tandem with PPS. Useful.
• I confirmed that two otherwise unrelated modules with fixes, do PPS exactly in tandem, as expected.
• Sentences output (at 1s intervals of 9600 baud) are ($GP)RMC, VTG, GGA, GSA, GSV & GLL. I only needed RMC & GGA.
• Position output was spot-on at least when static on my desk. Had no need to evaluate it in motion.
• Sentences seem to work fine with the usual GPS parsing libraries, or if you roll your own.
• The breakout module features what appears to be a small rechargeable coin cell spot-welded to its holder, permitting hot-starts.
• The supplied patch antenna on a short pigtail with a U.FL connector works well. So does a more substantial GPS antenna terminated with a U.FL. Keep in mind U.FL connectors are not intended for repeated mating cycles. ie, they’re fragile! Use a magnifying glass when connecting.

What I find questionable:
• Vendors’ Amazon description claims to be “using the original UBLOX (sic) 7th generation chip”. Obviously, the “GT-U7” module on this breakout board does not claim to be a u-blox product. Is it then using some sort of “original” ublox chip inside it? Reading up on how to spot a fake on ublox’s site leads one to believe this is in fact some sort of clone of the u-blox Neo 6 or 7. Startup $GPTXT sentence claims itself as u-blox 7, tho… Questionable if module is in fact configurable via u-center, although u-center has no problem parsing its output. If you are expecting something genuine-ublox, do some research.

• Questionable how 5V-tolerant RXD, the sole input on this breakout, might be. Since I do not plan on sending it any configuration, I’m leaving it disconnected and using the module in its default mode.

• A schematic of this breakout board would be very useful, in particular to answer the previous question. Can’t seem to find one for it. Aargh. Easy enough to reverse-engineer, given motivation to do so.

So, would I trust this product in my 1/8 scale autonomous jet-powered RC A380 model aircraft? Probably not.
But for my timekeeping application, it works fine, thus not subtracting any stars since I’m realistic about its pedigree.

Man, I just love these things. 5V friendly (which is a lot less common these days) and works beautifully with the TinyGPS++ library. Hunt down the ublox u-center software (it’s free) and you can make all kinds of tweaks to this thing. They’re so cheap, I’ve been using them for custom clocks. Never need to set the time! Even from a cold start in the basement with no saved ephemeris, GPS lock is achieved in minutes.

Update: one of my nanos was only putting out 4.2v on the 5v pin and that caused many problems including
very poor reception by this gps. If yours acts up check the voltage it’s getting.

Update: For my clocks I finally wrote my own nmea parser that only looks at the RMC messages. TinyGPS hides the actual message type from you, it waits until the age and error flags are all proper before it hands data off to you and it takes time extracting a lot of stuff I don’t care about. I have things to get done and TinyGPS was getting in the way.

20ma draw.

First (cold) start under a tin roof at 2000ft above sea level approx 10 min but may not happen at all until satellite view improves.

Warm start 10min later still under tin but against outside wooden wall is 5 seconds. 12 sats in view and 9 tracked.

‘Tepid’ start after being off overnight is about 5-10 seconds in the same conditions to emit time but getting the date takes maybe another 5 seconds.

Sentences with time appear as soon as the first sat is in view. (Nice for use as a clock source).

Hard to beat these modules for $13. Not sure if they’re knockoff UBlox modules or genuine with custom labeling, but either way they work great. I have been using them in a few different projects lately because they are 3.3v friendly, have a PPS pin, have both USB and UART, and they’re very sensitive. I have seen them continue tracking even with no antenna attached. The included pin header makes it easy to solder into a project.

The media could not be loaded.  This is the perfect GPS module for experimentation. It has both a USB and a SPI port. Starting off, check out U-Center SW. Using the SW, you can easily experiment and configure the module, learn what features it provides and just have fun. Later, you can connect to Arduino or Raspberry Pi using the SPI interface for your project. This module has great sensitivity. I tried placing it in the window sill which works, but I found that just placing it on a table near a window works fine as well.

The module I received had a u-blox NEO 7m module (not a 6m as stated in the product description)…but that’s a GOOD thing. The module does not have a u-blox label. (If the module is a Chinese knock-off of the u-blox product, it is an extremely good one. I’d bet that it is a genuine u-blox NEO 7m.)

The module comes with both a serial TX/RX interface AND a USB interface. I have used it on a Windows 10 machine with the u-blox u-center software, on a laptop running Ubuntu Mate, and on Arduino.

It was straightforward to get this working with Mikal Hart’s TinyGPS++ library. I’m using the module to get UTC time for setting a DS3231 RTC (real-time clock) chip. I only care about NMEA sentences that contain time and/or date information, so I rolled my own NMEA parser.

The USB port works great, as does the serial TX/RX interface. I haven’t tried using the PPS (pulse-per-second) pin yet, but I intend to use that to interrupt an Arduino to synchronize updates to an RTC.

This is a great u-blox module, and a great product. Highly recommended. My only minor complaint is that the documentation is very sparse, and written in Chinglish. I have no idea how the tiny on-board battery is being used, and how to save configuration data to the module (except through the u-blox u-center software).

This chip has pretty good warm and hot starts, your cold start will depend almost entirely on the antenna you use, although it’s usually 2-5 minutes under poor conditions. Without SBAS or RTK corrections it’s accurate to 2.5-5m, again depending on your antenna and sky conditions. It’s a Ublox neo-6m chip (or a clone of it). U-center works to configure it, and so does PyGPSClient. You can read serial data direct from it, and it can output NMEA or RTCM2 sentences (and of course UBX). It can take corrections, however, it must be RTCM2, which really isn’t supported by anything that’s actually respectable (most networked RTK solutions use RTCM3). Using RTKLib with corrections via NTRIP you can use RTCM3 sources as the processing is done on your computer instead of the GPS module. Here I’ve gotten 1 meter accuracy. A better antenna would likely improve this significantly, and you can use a U.FL to SMA to TNC adapter to use better more commercially available antennas.

All in all a great little unit for the cost. Just don’t expect to get mm level accuracy out of it. You’ve got to pay to play that game.

This is a great little GPS board…easy to use (standard NMEA output at 9600 baud) and sensitive. I live in a dense city area and I was able to get a lock by just halfway hanging the antenna out a window.

One of the best features of this board is the fact that you don’t have to solder anything to it if you don’t want to. You can plug a standard MicroUSB cable into the socket and it will power up and connect as a standard USB serial device (9600 baud) on any PC/Mac/Raspberry Pi/etc. This is PERFECT for your Raspberry Pi if you want to set up an NTP server or have a good position reference for something like FlightAware/Dump1090/MLAT.

All in all a really good product for the price. I would buy it again.
