Electronics question

[robinbanks]

So I have the guts from a little chinese toy camera drone. One of the components is a little piece of PCB with an antenna, 3 wires, and a ribbon cable with a camera lens. I'm assuming this is the module that creates the wifi network you connect to to view the camera feed. I would like to put this module on one of my toy helis, but I have no idea what to make of the 3 wires. Obviously 2 of them account for power positive and negative, but what's the 3rd wire for, and how can I accomplish my desired outcome?

Can you take some up close pictures both front and back for "us" ? If I had to guess in a 3 wire setup you have a +power...a Gnd and the third wire is "Trigger".

Board has it marked TX. I too figure it is to turn on/off the transmission.

So how do I get this board to work on my heli? Do I need to reconnect it with the rest of the drone stuff and see what happens on the TX line with my multimeter, and then see if that is feasible to reproduce on my heli?
