DJI Lightbridge documentation: https://www.dji.com/dji-lightbridge/info#specs

There are two systems: ground and air.

Setup:

• GoPro camera (microHDMI) → (microHDMI) Air system (TX) → (RX) Ground system (microHDMI) → (HDMI) DeckLink capture

Ground System

The ground system has an internal battery and is charged by a barrel plug. See input voltage on the unit.

Air System

I (Xierumeng) have no idea how the air system gets power (e.g. voltage?). There may be an internal battery.

The cable is labeled in the same manner the air system port is labeled:

• The white end plugs into the air system

• The red end plugs has 2 pins inside that may plug into a power source

• The yellow wires in the ribbon are not connected to anything
