Power DJI Transmission internally

3D Printed Mount
12V BEC
Angeled RED Komodo Power Cable
Micro JST GH1,25 6-Pin Connector
VBatt Power Cable with connector of your choice.

Open Up the front of the DJI Tranmitter and loosen the Screws holding on the Back Plate.

Remove the Back Plate and locate the internal connector connecting the LEMO Power connector to the PCB.

Remove the Connector from the PCB. To do so, press down on the small plastic tab and pull the connector out.

Prepare the new JST GH1,25 Power Lead. You will only need 4 of the 6 Pins. The two outer pins are not used.

For our units we used the following pinout, but it might be different for your unit. Please check with a multimeter before connecting the power lead.

Pin1: n/a
Pin2: n/a
Pin3: 12V
Pin4: 12v
Pin5: GND
Pin6: GND

Connect your Power Lead to the PCB. Make sure to connect the 12V Pins to the 12V Pins on the PCB and the GND Pins to the GND Pins on the PCB.

Turn your Transmitter unit around to make sure the connector is properly seated.

Prepare your BEC, Komodo Power Cable and VBatt Power Cable.

Feed your komodo power cable and your VBatt power cable through the hole in the mount.

Wire up the BEC to the Komodo Power Cable and the VBatt Power Cable. With the Caste Creations BEC, you might need to change it's output setting to 12V first.

Place the BEC in the Mount. Make sure to keep a bit of slack on the cables and leave room for the Transmission Pogo Connector.

Place the Mount on the Transmitter while making sure to not pinch any cables.

Srew on the Mount to the Transmitter and slide it onto the Camera. Connect the Komodo Power Cable to the Komodo and the VBatt Power Cable to your Battery.
