Geekstory BN-220 Dual GPS Glonass Module Navigation TTL Level 9600bps + GPS Passive Antenna for Arduino Raspberry Pi Pixhawk F3 CC3D Betaflight F4 Flight Control

Excellent Gps!, came to life the minute I plugged into Betaflight, the sticky back foam disk works great, Shipping was next day super fast!, couldn’t be happier!

Dont fly without gps. For less than $20 you can be certain your next flight wont be your last. Ps initial fix takes about 10 mins. After that quick fix is only a few seconds.

It says It comes with the USB link to flash the unit but I didnt receive one.

I am using this for a GPS device in my car that will light up the LED when I get close to key Points of Interest to remind me of things I keep forgetting (i.e. remember your Chuck-It when you leave the dog park). The picture is a prototype I whipped up to test the unit, as it is my first GPS project. I used arduino nano controller, with the NeoGPS library. Very easy to setup. My first satellite lock took less than a minute, and nearly instant when I am outside. It even gets a lock sitting on my desk indoors which was a surprise and helps for development.

I am using this on a boat. I used a usb to serial module to connect it to the u-blox connect software, so I could change the baud rate to 4800 which is the NMEA 0183 standard. Changes are stored in non volatile memory on this unit, which is not the case on some u-blox receivers.

Easy to install, using it to track speed, location and distance. Havent setup return to home in BetaFlight yet.

I like that GPS rescue mode it works pretty good

Did not do the job. Although I gave it very long time to do it (like 30 min), it could not connect to any satellites. Switched to a different GPS.

Put on my Diatone Roma F5 quadcopter. Wrapped in electrical tape for protection. It takes a couple minutes to get a gps lock even when i haven’t moved far, i guess it’s cause i don’t have it mounted in a perfect place but it gets the job done

I used this GPS module to make a 10 Hz GPS based automobile performance meter to measure accurate 0-60 times, 1/8 mile, 1/4 mile etc.
