Hello. I am going to use Orin Nano on my robotics project and I will power it with a battery which is also supplying other components of the robot. My battery is in 4s configuration; it can provide a maximum voltage of 16.8V, a minimum voltage of 12.8V and the current values are high enough.
My question is, I do not want to supply Orin Nano directly from battery because battery also supplies 8 big dc motors and I am worried that voltage/current spikes may damage the Orin Nano. So I will desing an power regulator board and provide a constant voltage to Orin.
Problem is that I cant figure out voltage I need. Orin’s specs says that it needs 5-20V input. Will 12V 5A supply be okay?
Thanks.

Based on the provided context, I’ll address your question comprehensively.
The Jetson Orin Nano module’s power requirements are specified in the documentation. According to the text, the module supports a voltage range of 5.0V to 20V on the VDD_IN pins. However, there’s a note that modules with pin 217 (Module ID) tied to GND support only 5V on VDD_IN, while modules with pin 217 floating (pulled high on the carrier board) support the full voltage range.
In your case, you’re planning to use a power regulator board to provide a constant voltage to the Orin Nano. You’re considering a 12V, 5A supply, but you’re unsure if it’s suitable.
Comparing the Orin Nano’s specifications with your proposed supply:
The Orin Nano supports a voltage range of 5.0V to 20V, and 12V falls within this range.
The maximum current requirement for the Orin Nano is not explicitly stated in the provided context, but it’s likely to be lower than the 5A you’re planning to provide.
Considering these points, a 12V, 5A supply should be okay for the Orin Nano. However, please ensure that your power regulator board can provide a stable and clean 12V output, as the Orin Nano is sensitive to voltage spikes and noise.
Additionally, keep in mind that the Orin Nano has a maximum power consumption of 25W (for the 4GB and 8GB modules) or 40W (for the MAXN_SUPER mode). Make sure your power regulator board can handle the required power and provide a sufficient margin for any unexpected peaks.
To summarize:
A 12V, 5A supply is within the supported voltage range for the Orin Nano.
Ensure your power regulator board provides a stable and clean 12V output.
Verify that your power regulator board can handle the required power and provide a sufficient margin for any unexpected peaks.
Please review the Orin Nano’s documentation and your power regulator board’s specifications to ensure a safe and reliable power supply for your robotics project.

Practically speaking, you very definitely want your power source to be isolated and very well regulated. Jetsons are particularly sensitive to regulation quality, and even if only the Jetson was present, then directly running from a battery (or even a mediocre regulator) would be a near guaranteed failure.
Those inductive loads, and even non-inductive loads that change, might even damage the unit. You are correct to wonder about that.
If the regulation quality is quite good, then 12V would work if the carrier board supports this voltage.
