Deegoo-FPV NEO-6M GPS Modules with Antennas, 2-Pack | Satellite positioning modules for Arduino-compatible boards, STM32 and UNO R3 projects with included antennas.

The most attractive feature for me was the USB. No need to wire it up to a USB-to-serial if you don't want to. Runs great on Win 11 with the Ublox U-Connect software. On my Linux machine, it shows up as /dev/ttyACM0. I can watch the GPS info scrolling by with this command: `(stty 9600 -echo -icrnl; cat) </dev/ttyACM0` I'm using it indoors, about a meter away from a window and getting several satellites. Accuracy seems good. If you want something easy, this is it. And at this price for two, you can give one to a friend.

Interfaced directly to sbc on windows ran immediately with no issues. additional freeware was needed to get the chip talking to windows as maps location. premium price fast shipping

Works very nicely as an ntp server on esp32 serving my offgrid cabin clocks and rpi’s. The 6M is pretty old stuff and not up to really precision timing but it’s good enough especially where internet is not available. A good ntp server is github “gps-ntp-eth-esp32” running on an esp32c3 Super Mini and one of these gps boards. Comment out all tft_espi references, the interrupt disable and enable calls, the PPS frequency. Change Serial2 to Serial1 and set its pin numbers (I use 1=txd 0=rxd). The tft_espi library does not work on c3 parts but I like them a lot and don’t have any displays handy anyway or any s2 mini’s for that matter. I ran the gps at its default 9600 baud with the PPS pin and it was stable. Then I upped the rate to 57k and disabled all the messages except RMC and GGA which contain the time data and spacecraft tracked respectively. Works a treat. A good ntp clock is github “tft_espi” and the example “Anti-aliased-clock” running on an esp32s2-mini (tft_espi does not work on the c3 part). I use that combination with Teyleten 1.28” round tft lcd displays to make miniature analog clocks. Add a voice JESSINIE 2Pcs DY-SV17F Voice Playback Module and a Gump's grocery 4pcs Micro Internal Magnetic Speaker to make it chime.

She indication of functional libraries would have made it a little easier. Otherwise, works great!!!!

Using these for time keeping with arduinos. Linked with windows laptop first to see lock and data transmission. (Drivers are really finicky and hard to get working though.) Eventually got these setup using an Arduino and was able to extract the time data from a lock and use it for a clock. (When there's a "lock", the RTC module gets updated with the current time if there's a certain offset). These work great and all lock family quickly even in my basement or living room within a minute. If outside they lock within 10 seconds. Very happy with these for various projects. Arduino libraries are full featured for these to get going quickly.

Two U-Blox 7 modules with antennas for 18 bucks, work as expected out of the box, no issues, nothing not to like. If you have a Linux box, you can get on the air with these babies in about 2 minutes: The first 1:55 with an eye loupe to connect the antenna, the last 5 seconds to plug it into a USB port. Reports USB device info as follows: idVendor = 0x1546 (U-Blox) idProduct = 0x01a7 (U-blox 7) which is then claimed by low-level ACM driver cdc_acm and shows up as /dev/ttyACMn, 9600 bps, 8N1. And at that point it's "just another GPS", and you can have fun with whatever userland utilities you like to configure and/or just gobble GNSS sentences (binary or NMEA, take your pick, U-Blox 7 supports both options.) Observed self-ID sentences immediately after power-up: $GPTXT,01,01,02,ANTSTATUS=OK*3B $GPTXT,01,01,02,u-blox ag - www.u-blox.com*50 $GPTXT,01,01,02,HW UBX-G70xx 00070000 FF7FFFFFo*69 $GPTXT,01,01,02,ROM CORE 1.00 (59842) Jun 27 2012 17:43:52*59 $GPTXT,01,01,02,PROTVER 14.00*1E $GPTXT,01,01,02,ANTSUPERV=AC SD PDoS SR*20 The very bottom line on the label of the units I received is 2311, probably a date code (i.e. November 2023) but not sure that's right. Not confirmed. Both the units I received obtained cold-start 2D fix in about 2 minutes, 3D fix about a minute later, indoors, above grade, with the supplied ceramic antennas. In steady-state, usually sees between 15-25 sats, uses 6 or 7. CEP is surprisingly large even with 6-7 sats, usually around 25m. Can't explain that. The actual reported location is within about 3m most of the time. For $9 each, what's not to like? Five stars.

Excellent well made, quick lock, versatile!

I purchased a package of two. Neither worked. Connected the first to USB. No power light. Not recognized by USB. Connected the second to USB. Power light came on solid, but never started blinking to indicate a location fix. No matter, it wasn't recognized by USB either. Returning to Amazon for refund.

Surprisingly easy to use. Quick satellite acquisition.

Todo bien

GPS works but u-center but impossible to upgrade the GPS firmware to the latest revision (and I have not found anywhere to get firmware upgrade on that chinese brand) nor deactivate beidou satellites. You can turn off all the other ones but not beidou. For my arduino experimentation, it's fine and precision is there with external antenna.

The product is great

Este Módulo GPS es mucho mejor que el NEO-6M. Este GPS si se conecta en cuestión de segundos aún en interiores a comparación del NEO-6M que estando en exteriores se tarda mucho en conectar. Lo recomiendo ampliamente!
