Powering the Nvidia Jetson Orin Nano Dev Board: IO Port and USB-C Options

Issue Overview

Users of the Nvidia Jetson Orin Nano development board are inquiring about alternative power supply methods, specifically focusing on the possibility of using the IO port or USB Type-C interface to power the device. This question arises in the context of custom design considerations, suggesting that users are exploring non-standard power delivery options for their specific applications or project requirements.

Possible Causes

1. Limited power supply options: The standard power supply method for the Jetson Orin Nano may not be suitable for all use cases, prompting users to seek alternative power delivery solutions.

2. Custom design requirements: Users working on custom projects or integrations may need to adapt the power delivery system to fit within specific form factors or power distribution schemes.

3. Portability considerations: Some users might be looking for more portable power options, such as USB-C, which is commonly used in mobile devices and laptops.

4. Power efficiency concerns: Alternative power delivery methods might be explored to optimize power consumption or improve overall system efficiency.

Troubleshooting Steps, Solutions & Fixes

1. Consult the Orin Nano Design Guide:

   • The primary resource for addressing power-related questions is the Orin Nano Design Guide.
   • This document contains detailed information about power part design requirements and specifications.
   • Users should thoroughly review this guide before attempting any custom power solutions.

2. Custom Power Design Considerations:

   • When designing a custom power solution, ensure that it meets all the requirements specified in the Design Guide.
   • Pay close attention to voltage levels, current capacity, and any specific power sequencing requirements.
   • Consider factors such as power stability, noise, and thermal management in your custom design.

3. IO Port Power Option:

   • If considering using the IO port for power delivery, carefully examine the pinout and electrical specifications provided in the Design Guide.
   • Ensure that the IO port can handle the required power delivery without risking damage to the board or connected components.

4. USB Type-C Power Delivery:

   • For USB-C power options, verify that the USB-C port on the Orin Nano supports power delivery functionality.
   • Check the maximum power output capabilities of the USB-C port and ensure it meets the board’s power requirements.
   • Implement proper USB Power Delivery (USB-PD) protocols if using USB-C for power.

5. Safety Precautions:

   • Always prioritize safety when experimenting with alternative power methods.
   • Use appropriate voltage regulators, current limiters, and protection circuits in your custom power design.
   • Test your custom power solution thoroughly before connecting it to the Orin Nano board.

6. Seek Official Support:

   • If the Design Guide doesn’t provide sufficient information for your specific use case, consider reaching out to Nvidia’s official support channels or community forums for expert advice.

7. Prototype and Validate:

   • Create a prototype of your custom power solution and test it rigorously.
   • Use appropriate measurement tools to verify voltage levels, current draw, and power stability.
   • Conduct long-term testing to ensure reliability and performance under various load conditions.

8. Document Your Findings:

   • If you successfully implement a custom power solution, consider sharing your findings with the Jetson community, adhering to any non-disclosure agreements or intellectual property considerations.

Remember that while custom power solutions may be possible, they should only be attempted by users with appropriate electrical engineering knowledge and experience. Improper power delivery can potentially damage the Jetson Orin Nano board or compromise its performance and reliability.
