HiLetgo NEO-7M GPS Satellite Positioning Module for Arduino STM32 C51 Replace NEO-6M 3.3V/5V Power Supply

I purchased 2 of these modules to work with an esp8266 mcu. It works great. I am using it with a Wemos D1 Mini with ESPEASY.

Worked Great. Yes you need to solder the SMA connector on it, and yes, you need an active GPS antenna. I Installed a different SMA connector than the one that was supplied (instead of angle one), installed the ublox driver (GNSS Sensor Device Driver), configured windows 10 to enable gps, and then started windows maps. GPS location worked right off. You can also use a Putty, or something that you can open a terminal serial window on the com port and see the raw GPS data. Everything worked as expected. To test with windows 10, look for the driver and how to configure, google "Connect a GPS/GNSS Receiver for Windows Maps " and this is the info I used. Thank you!

Il dispositivo funziona, ma solo se collegato ad una antenna esterna.Per cui procuratevi l'antenna (pochi euro anche qui) e mettete in conto di dover saldare il connettore SMA sulla scheda.C'è anche l'antenna ceramica montata direttamente sulla scheda, ma secondo me si sono dimenticati di collegarla: con quella da sola non otterrete mai il fix.Sarebbe da tre stelle per quanto detto sopra, ma ne aggiungo una per il convertitore USB onboard che rende superfluo il convertitore UART-USB indispensabile in molte altre schede.

As others have noted, the attached patch antenna pretty much does not work at all. Even leaving it outside for 20 minutes barely gave me a time signal (I have an RP2040 microcontroller application for displaying the GPS info). I pried off the patch and I though maybe the solder connection was not good, but even soldering a wire to ensure a good connection did not help. There is an onboard MAX2659 LNA for that antenna, so either that is not working properly or there is an issue with its interface to the NEO-7M module. Connecting an active antenna does work ok.
