Based on the provided context, the Jetson Orin Nano module requires a power supply with a nominal voltage of 5.0V to 20V, as stated on page 24 of the Jetson Orin NX Series and Jetson Orin Nano Series Product Design Guide.

The power supply you mentioned, which is a 12V 20A 250W regulated switching power supply, seems to be within the acceptable voltage range for the Jetson Orin Nano module. However, it’s essential to consider the following factors:

  1. Voltage tolerance: The Jetson Orin Module Data Sheet (not provided in the context) should be consulted for the supply tolerance. Ensure that the power supply’s output voltage is within the acceptable tolerance range.
  2. Maximum current: The power supply’s maximum current rating (20A) should be sufficient for the Jetson Orin Nano module. However, the actual current requirement depends on the specific configuration and usage of the module.
  3. Power mode: If you plan to use the Jetson Orin Nano Super mode, which requires a minimum of 8.0V to the VDD_IN, the 12V power supply should be sufficient. However, if you’re using the standard power mode, the voltage requirement might be lower.

To confirm the compatibility of the power supply with your Jetson Orin Nano module, it’s recommended to:

  1. Consult the Jetson Orin Module Data Sheet for specific power requirements and tolerances.
  2. Verify that the power supply’s output voltage and current ratings meet the module’s requirements.
  3. Ensure that the power supply is compatible with the module’s power mode (standard or super mode).

In summary, the 12V 20A 250W regulated switching power supply seems to be within the acceptable voltage range for the Jetson Orin Nano module. However, it’s crucial to verify the power supply’s compatibility with the module’s specific power requirements and tolerances to ensure safe and reliable operation.

If you are using the Jetson Orin Nano Developer Kit and connecting this power supply to the DC power jack of the Dev Kit, this power supply will work. The Jetson Orin Nano Developer Kit Carrier Board Specification specifies 9-20V for the DC jack in section 1.2 and a maximum of 4.2A in Table 5-2 (DCJ_IN).

If you are using a custom carrier board, you would have to conctact the manufacturer to determine the power input specs.
