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

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

Due to the complete lack of details on how best to utilize this module, i’m giving it this rating. While it’s technically possible to leverage the serial data this unit provides, it’s incredibly difficult to tap it for modern applications. If your building a Pi or Arduino application, don’t bother with this unit. Go with some USB or with something that includes documentation. Converting 232 serial data into a string using something like Python isn’t worth the hassle. This unit should be marketed more intentionally for the quadcopter crowd since they seem to be the only ones using it with the help of iNav.

Quick lock. Lots of sats and accurate positioning

Pretty easy to setup, only 4 wires to solder. As I recall, the diagram is from the bottom compared to when I was

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

Connects fast after the first time, wish the cable was longer...I lengthened it. I used it with the ZOHD Kopilot.

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.

as expected, just what i ordered.

If you are a part of the FPV drone world, you know breaking parts is part of the game. So this is my third GPS purchased and I have been happy with all 3. Works well, is accurate, and is durable. Definitely recommend!

Very good module. Works as expected. Easy to interface with raspberry pi.
