Powering Jetson Orin Nano Developer Kit Without Barrel Jack

Issue Overview

Users of the Nvidia Jetson Orin Nano Developer Kit are seeking alternative methods to power the device without using the standard barrel jack connector. This inquiry stems from a desire for more flexible power options, potentially for custom installations or specific use cases where the barrel jack may not be convenient or accessible. The discussion revolves around the possibility of using alternative power inputs, particularly focusing on the 40-pin header (J12) as a potential power source.

Possible Causes

1. Limited Power Input Options: The default power input method (barrel jack) may not suit all user scenarios, leading to the search for alternatives.

2. Custom Installation Requirements: Some users might need to integrate the Jetson Orin Nano into systems where traditional power connectors are impractical.

3. Barrel Jack Damage: In some cases, users might be seeking alternatives due to a damaged barrel jack connector on their device.

4. Power Supply Flexibility: Users may require more flexible power supply options for portable or embedded applications.

Troubleshooting Steps, Solutions & Fixes

1. Official Power Method:

   • The primary and recommended method for powering the Jetson Orin Nano Developer Kit is through the barrel jack connector.
   • Ensure you are using the correct power supply specifications as provided in the official documentation.

2. Alternative Power Method (Not Supported):

   • Initially, it was suggested that pins 2 & 4 of the 40-pin header (J12) could be used to supply 5V power to the board.
   • However, an important update was provided: For the Orin Nano, powering the device through the 40-pin header is no longer supported.

3. Recommended Action:

   • Stick to using the barrel jack connector for powering your Jetson Orin Nano Developer Kit.
   • If you absolutely need an alternative power method, consider reaching out to NVIDIA support or consulting the official forums for the most up-to-date information and recommendations.

4. Custom Power Solutions (Caution Required):

   • If you’re considering custom power solutions, exercise extreme caution as incorrect power supply can damage your device.
   • Any modifications to the power input should only be attempted by those with advanced electronics knowledge and at their own risk.

5. Documentation Review:

   • Thoroughly review the latest official documentation for the Jetson Orin Nano Developer Kit.
   • Check for any updates or revisions to the power supply specifications and supported methods.

6. Community Resources:

   • Keep an eye on official NVIDIA forums and community discussions for any future updates or officially sanctioned alternative power methods.
   • Be cautious of unofficial modifications or suggestions that haven’t been verified by NVIDIA.

7. Hardware Inspection:

   • If you’re having issues with the barrel jack, inspect it for any physical damage or loose connections.
   • In case of damage, consider professional repair services rather than attempting unsupported power methods.

Remember, using unsupported power methods can void your warranty and potentially damage your device. Always prioritize official power supply methods and consult NVIDIA support for the most accurate and up-to-date information regarding your Jetson Orin Nano Developer Kit.
