Assembly Instructions
As we do not provide ready-to-use assembled CamAdapter, the end user is to assemble it
himself.
Attention: There are some parts which should be manufactured using 3D-printer. Also, there
are cover boards which are to be milled with CNC machine or ordered as PCB.

Jetson Edition
This edition of CamAdapter is based on NVIDIA Jetson TK1.
Important notice
€ The software is compatible only with NVIDIA Tegra K1 platform at the moment.
€ This version of CamAdapter supports DJI Zenmuse X3/X5/X5R/XT/Z3 only.
€DJI Zenmuse Z30 is supported using a special adapter. Note that the current hardware
design does not suppose this adapter to be mounted. One needs to develop a custom
design in order to connect Z30.
€ Tested with DJI Zenmuse X3/XT/Z3.

Schematic
Step-by-step assembling
1. Desolder COM and audio connectors from Jetson TK1 and solder fan wires directly to the
receptacle in order to reduce overall board height.

2. Remove DJI Mounting Board from the bracket.
3. Mount DJI Mounting Board under the bottom board using screws (holes are marked red).
Pass power cable through the hole marked green. Connect video and CAN-bus cables.

4. Place box part onto the bottom board then mount Jetson TK1 onto them and fix with M3
screws and bars.
5. Insert EMUC-B202 board to the mPCIe slot. Fix it with M3 screws and nuts inserting
EMUC spacer between EMUC and the bottom board. Connect the video cable to
micro-USB connector on Jetson and CAN-bus cable to the top connector on EMUC-B202.

6. Mount DC-DC onto the top board and fix using M3 screws and nuts. Solder power wires
from DJI Mounting Board and input power wires to IN+/IN- pads and Jetson power cable
to OUT+/OUT- pads.
7. Close the box with the top board and fix it using M3 screws.
8. Fix ear boards under the bottom board inserting rubber dampeners.

9. Mount assembled device on DJI S900 frame inserting ear spacers and connect power and
Ethernet cables.
Stabilization
In order to stabilize the gimbal against drone inclination one need to use separate AHRS
device. One may use a flight controller for that purposes. There is a special software which
gets attitude information from autopilot and sends it to CamAdapter. See attitude-feeder
application for details.
