Andruav
Android companion computers for drones & RC vehicles
...It saves you a lot of gear and wiring by replacing dedicated FPV equipment, telemetry radios, and ground stations with a single Android phone.
What you need
Just two Android devices running Andruav:
One device stays on the vehicle as the companion computer — connected to your flight controller over USB, streaming FPV video from its camera, and relaying telemetry.
The other device becomes your ground station — displaying live video, telemetry, map position, and flight controls.
The two devices talk to each other over WiFi or 3G / 4G / 5G, giving you telemetry range limited only by your mobile network instead of your radio.
