I want to collect GPS data with a cellular-enabled micro-controller to help me find my drone if it gets lost. My drone has GPS, so I tried to connect to it. Many GPS break-out boards have the following connections:
Some of the time there are more, but these seem to be the essential ones. But, I'm studying a GPS module that uses only 3 wires. Take a look:
The red and black ones are power and ground. Must the remaining wire be TX?
I've been trying every way I can think of to tap into this GPS on my quad. I spliced into the 3 wires, but I only connected ground and what I suspect to be TX to my micro.
Also, at this point, I'm just curious.
I've studied the GPS a bit more and I can now see it has a compass and some other motion device. So it's not just a GPS board. It also had it's own micro controller managing all of these devices. I think the serial data on the wires I've tapped has been reformatted for the flight controller. It's gibberish in the arduino app.
At this point I'm ready give up and just put a second GPS on the thing! But before I give up I wanted to ask if there are any other methods I can try to listen to the GPS.
