DIYmalls BN-220 GPS Module TTL Dual GPS Glonass w/Flash NMEA-0183 9600bps 1Hz for Arduino RC FPV Drone Flight Control

I didn’t want to have to wire all the way to my second helm station, so I used this to add GPS for the DSC function on a marine VHF radio. It worked great. I do have to kill the radio breaker when I want to shut it off, but that’s fine. The radio comes on with the breaker too and I no longer use the knob to turn it in and off. It works.

I was disappointed that the Tyt MD9600 ham radio I bought didn't include GPS, so I bought this to mod it. It worked perfectly, requiring that I only solder the wire for power, ground, and TXD (the radio never sends data to the GPS, so the RXD wire is not necessary.This thing is better than I dared hope. It locks on 7 sattelites in less than a minute from within my garage and inside our SUV. I call that a win!

I mounted this inside of my autonomous airplane, hoping for maximum water resistance and to my astonishment it still was very prescient inside faced down as I did not know which way to point it. Five stars.

This is the device that I used to build the GPS for my Icom IC-7100 radio.

When wired properly it works great!

I have bought 5 of the BN-220 GPS modules over the past 3 years. Some to replace failed modules and some for new projects. Of the 5 I bought, only 2 worked when I received them. I have tried programing the settings of the 3 bad one's, but that made no difference. I have decided to spend a little more money and get better GPS modules like the Matek M10Q-5883.

The wire are stout with the connector s. The GPS acquires lock within a few minutes. Good lock is a flashing Red light. I flew tactical just, flashing Red light should be changed to Blue, Green almost anything but Red...
