Power plan for Jetson Orin

Robotics & Edge Computing Jetson Systems Jetson AGX Orin

Hello,

We are currently using the Jetson Orin Development Kit 64GB and have some inquiries regarding its power specifications. We intend to use this kit in a product we are developing, which requires operating while being powered from a DC-DC converter (specifically TDK Lambda’s DDA325N-D2PN-1212-001) as we are trying to replace the provided power cable with the adapter.

I was following these posts:

My question is whether it is ill-advised to use a non-standard DC plug (one that can handle 20V-4.5A) with free leads going to the screw terminals on the power supply converter? What are some precautionary procedures I should take if it is feasible?

P/S: whether cutting off the female end to get the free leads out to the converter like this is okay or not?

Based on the provided context, I’ll address your questions regarding the power specifications of the Jetson AGX Orin Development Kit 64GB and the feasibility of using a non-standard DC plug with a DC-DC converter.

Power Specifications:

The Jetson Orin Module Data Sheet specifies that the module is powered through the VDD_IN pins, with a nominal voltage range of 5.0V to 20V. However, to operate in MAXN mode, the Jetson Orin NX requires a minimum of 8.0V to the VDD_IN.

For the Jetson AGX Orin, the recommended power supply voltage is not explicitly stated in the provided context. However, based on the posts you mentioned, it seems that the correct DC jack voltage for Jetson AGX Orin to run in MAXN mode is not clearly defined.

Using a Non-Standard DC Plug:

Regarding your question about using a non-standard DC plug with a DC-DC converter, it’s not recommended to use a plug that can handle 20V/45A with free leads going to the screw terminals on the power supply converter. Here’s why:

  1. Voltage Rating: The Jetson Orin module is designed to operate within a specific voltage range (5.0V to 20V). Using a plug that can handle 20V/45A may exceed the recommended voltage rating, potentially damaging the module.
  2. Current Rating: The Jetson Orin module’s power consumption varies depending on the operating mode. Using a plug that can handle 45A may not be necessary, and it may also cause overheating or other issues.
  3. Safety Concerns: Using a non-standard DC plug with free leads can create safety hazards, such as electrical shock or fire risks.

Precautionary Procedures:

If you still want to use a DC-DC converter with a non-standard DC plug, follow these precautionary procedures:

  1. Verify the Voltage and Current Ratings: Ensure that the DC-DC converter’s output voltage and current ratings match the Jetson Orin module’s requirements.
  2. Use a Suitable DC Plug: Choose a DC plug that matches the Jetson Orin module’s power connector and is rated for the required voltage and current.
  3. Avoid Overheating: Ensure that the DC-DC converter and the Jetson Orin module are properly cooled to prevent overheating.
  4. Follow Proper Wiring and Safety Guidelines: Ensure that the wiring is done correctly, and follow proper safety guidelines to avoid electrical shock or fire risks.

Cutting Off the Female End:

Regarding your question about cutting off the female end to get the free leads out to the converter, it’s not recommended. This can create safety hazards and may damage the DC plug or the converter.

Instead, consider using a suitable DC plug that matches the Jetson Orin module’s power connector and is rated for the required voltage and current. This will ensure a safe and reliable connection.

In summary, while using a non-standard DC plug with a DC-DC converter is not recommended, you can follow the precautionary procedures outlined above to minimize risks. However, it’s always best to use a standard DC plug that matches the Jetson Orin module’s power connector and is rated for the required voltage and current.

Please refer to the guidance in the post by @carolyuu. Cutting cables is not recommended.

The Jetson AGX Orin Developer Kit Carrier Board Specification has some additional information about the DC Jack that may be useful:

Got it.

We usually have it powered from ~120VAC standard home power supply with the given AC adapter to USB-C. Would you have any firm recommendation for our Edge computing use case where we want to power with either a Type-C/DC jack power cord with the live wires connected to a converter/ power supply box that matches 20V 4.5A that will be put inside an electrical cabinet?

May I have any reference to projects that do not use the conventional provided AC adapter that may revolve around that supposed idea? Or would it be more of a problem with getting a higher quality cable?

We are trying to run an additional DeepStream pipeline along with a small Edge server for communication to the mother server elsewhere through the Internet.
