Jetson orin nano developer kit, external power

Hi all,
I’m using the whole dev kit on a bigger carrier board, and would like to power it also from the bigger carrier.
Question is, are there any pins to do so? I have on my carrier 12V/5V/3v3 already. How to wire that up?
Or, should a just bridge the 12V on my carrier to the barrel connector on the dev kit?
Thanks!

Based on the provided context, I’ll try to help you with your question.

It appears that you’re using the Jetson Orin Nano Developer Kit on a larger carrier board and want to power it from the larger carrier board instead of using the DC power jack on the dev kit. You have 12V, 5V, and 3.3V power rails available on your larger carrier board.

According to the context, the Jetson Orin Nano carrier board has a few power-related components:

  1. DC_IN (Component): The main power input from DC Adapter
  2. VDD_5V_SYS (Component): The main 5.0V supply
  3. VDD_HV (Component): (No description available)

Since you want to power the dev kit from your larger carrier board, you’ll need to connect the power rails to the corresponding pins on the Jetson Orin Nano carrier board.

Unfortunately, the context doesn’t provide a clear pinout or schematic for the Jetson Orin Nano carrier board. However, I can suggest a few possible approaches:

  1. Check the Jetson AGX Orin Series Developer Kit Carrier Board Design Files (A04) (Document) for the schematic and pinout information. This might give you an idea about the power pins on the carrier board.
  2. Look for the J14 (Component) header on the Jetson Orin Nano carrier board, which might have some power-related pins.
  3. If you have the P3737_A04_Concept_schematics.pdf (Document) file, it might contain the schematic for the P3737 carrier board, which could be similar to the Jetson Orin Nano carrier board.

As for bridging the 12V on your carrier to the barrel connector on the dev kit, it’s not recommended without proper understanding of the power requirements and voltage regulation on the dev kit. The dev kit might have specific voltage regulation and power sequencing requirements that need to be met.

To summarize:

  • Check the design files and schematics for the Jetson Orin Nano carrier board to find the power pins.
  • Be cautious when connecting power rails from your larger carrier board to the dev kit, as voltage regulation and power sequencing might be critical.
  • Avoid bridging the 12V directly to the barrel connector without proper understanding of the power requirements.

If you have any further questions or need more specific guidance, please provide more information about your setup and the documentation you have available.

Power delivery or power tree design for your bigger carrier board is your system design choice. We do not have any recommendation. You will need to figure out what works best for you and meets your design needs.

I wasn’t asking how to design my own part. My question is, where/how best to connect it to the carrier, as I don’t see any external power pins/vias besides of the barrel connector.

So far, I think I should really connect my 12V to the barrel connector, as there doesn’t seem to be any other alternative

Using barrel connector is the correct choice in this case.
