The AEO G-OSD 3 is a very lightweight and easy to use OSD. It is feature packed and includes a GPS and Voltage monitor so you will know exactly what is going on with your batteries.
The included GPS has a high speed refresh rate and displays location, number of satellites and distance from home! It also shows the home direction. The airspeed and altitude is also displayed.
The included voltage sensor comes with ultra plugs attached, so you may need to make an adapter or remove them if you use another battery type. The OSD can monitor 2 voltages such as your camera battery and flight battery. This will show the voltage for 2 batteries and the mAh consumed for 1 battery.
To complete this project have some spare male servo extensions available to use to connect the camera or other devices to the OSD. Take your time and READ the directions!
