M80 Pro GPS

I have bought plenty of the iflight gps receivers in the past just because I like the brand but I decided to try this one because of it's price. SO MUCH BETTER. Locks faster, more accurate, and cheaper!I have read some of the reviews saying to use NMEA instead of UBLOX but I could not get the NMEA to work, the instructions that are included say to use the UBLOX. So that's what I did and it worked perfectly.The included cable's pinout did not match my FC so I had to change that around a bit but it was an easy and acceptable fix. Just don't plug yours in and short something out, always check your wiring diagram.I will be buying more and slowly replacing my iflights.

Small form factor. Compass is accurate and supports 800khz i2c bus. works great on my quadcopter using betaflight

This is the most accurate GPS module for FPV I have ever had. I have tried the Matek M8Q-5883 and had mixed results. This M80 Pro gets a stronger and faster lock. The magnetometer is spot on, even in my planes. This is a wonderful unit.

I cant rate the durability because i hooked this to the wrong port! Be careful not to plug it into the DJI air plug on the Flight controller! It will instantly turn this unit into junk with a green light. Betaflight will not detect this unit once it's been hooked up wrong even though the green led still lights up! I'll just have to fly without GPS for now!

Supports Mag and Barometer, and has compass. Best GPS unit yet. I will buy this unit going forward as I continue to build out my FPV quad collection.

The GPS portion worked fine, albeit slow. The magnetometer would work for a minute or two, but then stop. Not only that, but it would take the barometer down with it. I moved it off the dedicated i2c pads on the flight controller and converted SERIAL 3 into a i2c bus. It worked, but still stopped after a minute. Then I turned on the built in pull up resisters. It lasted two to four minutes, but still stopped. At least it didn't take the barometer down with it. I flashed tried the latest iNAV instead of Betaflight and the exact same problem happened.I'll get a Matec or something proven to work next time.

These modules lock fairly quick

I was having trouble getting this to work, for a week or so now. I finally checked the pinout of the connector and the flight controller side connector (SpeedyBee F7 flight stack). The pinout was way off, which is why the GPS didn't even light up. Using an exacto knife, I carefully lifted the plastic tabs on each wire and removed them cleanly. I then referenced the circuit board itself, which explains the pinouts for the F7 flight controller (+5v, ground, TX, RX, SDA, SDL).Make sure to flip the TX and RX lines, from the GPS. (example: You want the TX of the GPS to hit the RX of the Flight controller)
