I've got a Heliway 901S (clone of the FQ777-FQ11 foldable nano quadcopter), which has FPV over WiFi. It can be controlled via a wifi app or the included transmitter (or my Jumper T8SG). Inside the quad there's two antennas on two separate PCBs. The WiFi PCB is only connected to the flight controller via 3 wires, marked "PP", "PV/3.0V" and "PG". I'm guessing this will be a PPM signal but at 3 volts instead of the standard TTL. The reason why I'm reverse engineering this is that the FPV over WiFi is not low enough latency to fly decently, so I want to remove that board for use on an extremely small telepresence robot. I should be able to still fly the quadcopter with a transmitter and add a proper 5.8GHz camera.
Has anyone done this already? Are these WiFi PPM/FPV receivers available separately so I can use them on other projects?
