I’d be happy to help you with your questions about powering the Jetson Orin Nano.
Powering the Jetson Orin Nano through the USB Type-C port
The Jetson Orin Nano can be powered through the USB Type-C port, but it’s essential to ensure that the power supply can provide sufficient power to the board.
The Jetson Orin Nano’s power requirements are not explicitly mentioned in the provided context, but we can infer some information from the INA3221 power monitor’s capabilities. The INA3221 is a three-channel power monitor, and its sysfs nodes can be used to read the rail names, voltage, current, and instantaneous and average current limits.
Assuming the Jetson Orin Nano’s power requirements are similar to those of the Jetson AGX Orin Industrial, which is mentioned in the context, we can estimate the power requirements.
The Jetson AGX Orin Industrial’s power rail for TMP451 is always on, and powering the board without sufficient cooling can cause it to fail. The default hysteresis is 10 degrees Celsius, and the board can be powered on again only after the temperature falls below the (threshold - hysteresis) degree Celsius.
While the exact power requirements of the Jetson Orin Nano are not provided, it’s likely that the board requires a significant amount of power to operate, especially when considering the power requirements of the TMP451 power rail.
In your case, the power bank’s 20W output might not be sufficient to power the Jetson Orin Nano, especially if the board is not properly cooled. A 5V 5A power supply might be sufficient, but it’s essential to ensure that the power supply can provide a stable and sufficient voltage and current to the board.
Using the DC barrel jack instead
If you decide to use the DC barrel jack instead of the USB Type-C port, you’ll need to ensure that the power supply can provide a voltage and current that meets the board’s requirements.
The recommended voltage and current specifications for the Jetson Orin Nano are not explicitly mentioned in the provided context. However, based on the information provided for the Jetson AGX Orin Industrial, it’s likely that the Jetson Orin Nano requires a voltage higher than 5V to operate.
A common voltage range for the Jetson Orin series is between 9V and 20V, with a recommended voltage of 12V. However, it’s essential to consult the official documentation or contact the manufacturer to confirm the recommended voltage and current specifications for the Jetson Orin Nano.
Using a buck converter
If you decide to use a buck converter to power the Jetson Orin Nano, you’ll need to ensure that the converter can provide a stable and sufficient voltage and current to the board.
The output voltage and current specifications of the buck converter will depend on the specific requirements of the Jetson Orin Nano. If you’re using a 5V 5A power supply, you might need to configure the buck converter to provide the same output voltage and current.
However, if the Jetson Orin Nano requires a higher voltage, you’ll need to configure the buck converter accordingly. It’s essential to consult the official documentation or contact the manufacturer to confirm the recommended voltage and current specifications for the Jetson Orin Nano.
In summary, while the Jetson Orin Nano can be powered through the USB Type-C port, it’s essential to ensure that the power supply can provide sufficient power to the board. A 5V 5A power supply might be sufficient, but it’s recommended to consult the official documentation or contact the manufacturer to confirm the recommended voltage and current specifications.
