Using MIPI CSI-2 Cameras with the NVIDIA Jetson
Unlike other camera types such as USB or Gigabit Ethernet, there isn’t a universal or standard connection for the different MIPI camera connectors from vendor to vendor. When working on an embedded vision application, this can make finding standard hardware for projects confusing. Depending on the Jetson module you’re developing on, the requirements for selecting a compatible MIPI camera will differ.
There are three scenarios for using MIPI CSI-2 cameras with standard carrier boards: on-board connection, conversion boards, and expansion board.
Since the connector cable pinout for MIPI cameras tend to be vendor specific, many carrier boards will require either a conversion board or an expansion board to be attached to the carrier or system to allow for your preferred camera model. Many camera vendors will have an expansion (or adapter) board that will allow you to connect directly to the NVIDIA Developer Kit, and these boards may or may not be compatible with your deployment Carrier Board. Alternatively, a conversion board that simply changes the connector type can be used. Lastly, in some cases the Carrier Board will have a specific connector that allows for direct camera connection; eliminating additional stacks on your device.
On-board VS Expansion Board Example
Cable connects directly into Carrier Board
On Board Example
Expansion Board is installed on the Carrier, and cable connected to expansion board
Expansion Board Example
To simplify the options, only some modules in the Jetson lineup will allow for direct on-board camera connections:
|Product||MIPI Connector||Connection Options|
|Jetson Nano Developer Kit||MIPI CSI (15-Pin Connector)||On-board or conversion board|
|Xavier NX Developer Kit||MIPI CSI (15-Pin Connector)||On-board or conversion board|
|TX2 Developer Kit||MIPI Expansion Slot (High-density camera connector breakout)||Expansion board only|
|AGX Xavier Developer Kit||MIPI Expansion Slot (High-density camera connector breakout)||Expansion board only|
As more complex vision applications are being designed, customized hardware stacks with Carrier Board and multi-camera Expansion Boards are in high demand.
As the NVIDIA Jetson platform grows, more camera vendors are developing models that allow for direct connection to the Developer Kits. We’ve developed Carrier Boards that utilize vendor specific connectors, allowing for an easy to integrate hardware stack.
Below is a list of our off-the-shelf commercial Carrier Boards organized by their connector type:
|Connector Type||Jetson Nano/TX2 NX/Xavier NX||Jetson TX2||Jetson AGX Xavier|
|MIPI CSI (15-pin Connector)||Quark
|MIPI Expansion Slot||Elroy
|I-PEX 30-Pin (FAW) Cable||Spacely
|FRAMOS Specific Connector||Boson for FRAMOS|
|Allied Specific Connector||Allied Vision MIPI Camera Board|
Once you select your preferred camera model, simply determine the cable connector type to find a compatible Carrier Board.

Once you have determined that your solution is compatible via hardware, there will likely be some software development required to use that camera with your application. As a general rule, if you get your camera working on a Jetson Developer Kit, it will be compatible with a Carrier Board for deployment. Beginning with the camera drivers, you can develop the software for successful communication with the Developer Kit. Once you move your application for deployment, there is a specific board support package (BSP) unique to your chosen module and JetPack version. BSPs are included with the purchase of a Carrier Board, but they do not include software specific configurations for all MIPI cameras on the market. Connect Tech has a range of camera models that have software hooks included within the BSP, eliminating the need for further integration development. Visit our Supported Cameras page to learn more.
You can choose to either self-develop or contract the software development for successful implementation of various camera models.
If you choose to self-develop the required software, we provide the source code for the BSP to help you with this process. In many cases, it is not only faster but also cheaper to contract us to develop the software to integrate your chosen cameras.
