I've worked with a few different GPS modules. Most of them seem to just pump out data and not really interact with the micro controller.
I have a quadcopter (Cheerson CX 20 Big Sky) It has a gps break out board that looks similar to the one I've worked with before. Is it likely that I connect another micro controller to this board? I want to add a cellular module to my quad.
I know that the answer may be "it depends" but before I start testing and researching I just want to know if it's even likely to work.
If the gps is just barfing out coordinates and not interacting with the main board I think it could work. I could just tap in and "listen" -- is this even a possibility?
