HiLetgo GY-NEO6MV2 NEO-6M GPS Flight Controller Module 3V-5V with Super Strong Ceramic Antenna for Arduino EEPROM APM 2.5

For such a large ceramic dish I would expect more accuracy but still 5 stars. However setup was easy and works well! A little c++ to fetch and display some logic helps to make an excellent speedometer. I originally got it for more accurate applications such as drawing images based on network coordinates... Didn't work too well it jumps a lot. Had to wait about 8 minutes to get a good lock the first time (maybe the battery was recharging idk). Connected to 6 satellites generally gives me consistent accuracy to 1 or 2 meters. Will purchase again because of the price point. i am able to usually get 11 on a clear day.

Worked the first time! I had need to add GPS capability to my Cubesat simulators. I use these simulators as a demonstration to various high schools in the area. The sat simulators had every capability except for GPS position reporting. The HiLetgo GY-NEO6MV2 NEO-6M GPS Flight Controller Module fit the small spaces and programmed easily (Direwolf for those curious).

Didn't work following instructions on an ESP32 dev board; couldn't get a lock after 72 hours. Tried using an Arduino Mega 2560 dev board instead and obtained a lock after 15 seconds.

I wanted a GPS receiver that would work with both a PC and with an Arduino or other embedded board. The GY-NEO6MV2 GPS sensor board is ideal for almost any application, though you do need a small amount of skill to wire it properly. I gathered a USB serial adapter that has TTL input/output levels and that can furnishe +5V to the GPS board together with some connecting wires (power, ground, Tx are required and Rx is optional). I connected the GPS board to the USB adapter as you can see in the photo above. When connected to my PC, I used two different programs to verify operation. UBlox provides a free download, called u-center, that has many useful features. One picture shows it in operation. The other two pictures are from a progam that I wrote (you can ge more information from my profile) that allows me to display my current position on a map (Google maps, Bing maps or other mapping solutions are possible) along with a simple text display that shows interesting data derived from the GPS receiver output, such as speed, course, altitute, and number of satellites in view. Why do I find this board to be such a good solution? There are three reasons. First, it is low cost and delivery in the US is very quick through Amazon. Second is its superior performance. All of the images above were generated at my home-office desk located in the basement. Other GPS receivers do not function well in this location because the GPS satellite signals are partially blocked by the structure of the building and by locatation in a basement with no clear view of the sky. Third is the ceramic antenna that is provided with the board. I believe that this antenna design contributes significantly to the superior performance of the GPS receiver as a system. I am truely impressed.

If you're buying this, maybe your a tinkerer and/or enjoy soldering building projects etc. Well, if you're not familiar with reflowing ICs, SMDs, BGPs, then here's an expensive way to learn. Initially, I wired up my GPS to my pico, and after letting it 'warm up' for two hours, it never saw any sats, no LED activity, etc. I then tried to connect it to my windows PC and used the u-center from ublox. Again, nothing. It couldn't even read anything from the ublox module. After inspecting carefully, the package was in fact soldered, but maybe only one or two pins were correctly aligned. I'm very familiar with reflowing, and did it professionally so no problem, before I complain and return it, I'll give a reflow a try. Low and behold, reflowing did the trick. Nearly instantly I got 4 sats locked (Northeast US) and after another 30 seconds the little led started flashing, and the u-center software shows 13 sats locked. Location seems to be accurate within 6 meters, time is dead on. I purchased this to make a 'stratum 1' ntp server for my homelab, so hooking it back up to my pico and it worked fine. Since I'm not concerned with location, accuracy was not important to me, only UTC time. I'm also using 3.3v but it does appear that it should be fine with 5v input, given the fact they couldn't correctly install the package, I'm not leaving it to chance. If it worked out of the box, I would have given it 5 stars, but with some handy work, I only give it two. Many people do not have the skills or tools to reflow a product that should have worked out of the box. Additionally, another reviewer posted a photo of a new label attached to the package, mine also has a new sticker. These are likely pulled units and needed a new sticker either because the manufacture had updated the firmware, and or, they themselves are not good at reflowing and used too much heat which burned up the original sticker (that's what mine looks like) and to make it 'new' they put a new label on it. Buyer beware. This seems to be a luck of the draw product and be prepared to either reflow or return yours. I wish I had a photo of before vs after.

Works like a charm. For those of you who think the board is a dud and nothing seems to be happening (like not even the LED blinking) - it takes a couple of minutes when you first fire it up to start getting a hold of the satellites - make sure to put the device near a window at least. There's also an onboard battery, which likely is flat on arrival. It needs a couple of hours of continuous activity to get it charged. Don't give up, it's a very nice little module with a lot of great uses! I hooked mine up with a Wemos D1 mini and it's a great pairing, GPS+WiFi. Add a battery and you have yourself a nifty, portable GPS tracker. Add a GSM module, and you can get a location reading from anywhere! The possibilities are endless :) Look into TinyGPS++ on github

There's no 4 pin connector to solder on ... really

Funcionó pero dejó de funcionar a la semana

電源接続して窓際に置き10分か20分で測位が成功し、LEDが点滅するようになります。これは初回のコールドスタートなので次回以後は30秒もかかりません。 Windows PCでUSB-3.3V TTLシリアルドングルを接続しCOMポートをTeraterm で9600bpsにセットすればNMEAフォーマットのデータが読み取れますし、ublox社のu-centerをインストールすればより詳しい情報がグラフィカルに表示されます。 Raspberry Piに接続してntpdをGPSに同期させてみました。 LEDのところにでているPulse Per Secondの信号をジャンパ線で取り出してRaspberry Pi のGPIO18ピンに接続し、このボードのTXから出ている信号をRasberry pi のRXで読むように結線します。 その他電源5V、GNDもRaspberry Piから供給します。 gpsd 経由でNMEA データを読み取り、/dev/pps0 デバイスでPulse Per Secondの信号を使って調律することでusecオーダーでGPS時計に同期しているようです。 結線作業に失敗してつぶしてしまってももう一枚気軽に買えますね。気に入りました。 追記 9600bpsで出力されるNEMAフォーマットのデータをArduinoで読み込みI2Cバスで他のArduinoに位置情報を提供するI2C-GPS-NAVというのも試してみました。メインCPUが姿勢制御で忙しいロボットで自律帰還遊びに活用できました。 さて次は上位機種のNEO M8N を買おうかと探していますが、amazonで売っている他社製品はレビューアの投稿写真を見るとfake品でした。ublox neo m8n fake でググっていただければ判別方法がわかります。 追記 マルチGNSSのM8N相当の性能のものはM5stack.comから出ているAT6558採用のGPSモジュールが検討に値します。

This device is scratched and the LED does not work, and when I attempted to use it, it gave me incorrect coordinates (I am an electronic technician and I am sure of the connections and the code).

Can't change baud rate
