For Jetson Nano Developer Kit (945-13450-0000-100) customers intending to purchase Jetson Xavier NX module, please consider:
Jetson Xavier NX module does not include a heatsink
The expectation is that customers will design or procure a thermal solution appropriate for their particular application. Please read the Jetson Xavier NX Thermal Design Guide.
Off-the-shelf thermal solutions for Jetson Xavier NX are available from Jetson ecosystem partners. Check this wiki page for a list.
The Nano devkit reference carrier board has power limitations
The Jetson Xavier NX module supports up to 15 W power budget. You’ll definitely need to use the barrel jack power supply connector on the Jetson Nano Developer Kit carrier board.
Use a quality power supply like the ones we list in Jetson Nano SCL, but take note that the Jetson Nano Developer Kit User Guide specifies a maximum supported continuous current of 4.4A for the Nano reference carrier board. This means 7 W will be your max budget for everything other than the module, e.g., peripherals, Ethernet, the carrier board itself, etc.
Jetson ecosystem partners offer carrier boards for Jetson Xavier NX. Check this wiki page for a list.
[EDIT - updated with link to off-the-shelf thermal solutions and carrier boards]
I’m confused by your answer. I saw the guide says the maximum supported currrent is 4.4A @5V, how is the capacity of 7W calculated? I thought it’s equivalent to 22W.
On the other hand, the new 2GB kit comes with USB-C power connector, is it “plain” USB-C or Power Delivery compliant? The guide is not revised to reflect the update.
Regarding your 7W question: This is the power budget remaining if you run the Jetson Xavier NX module in 15W mode while attached to the Jetson Nano Developer Kit reference carrier board.
I was wondering if it was possible to use the Nano carriers for the NX modules but read on the Nano carrier board (next to the power connector) “Max 5V”.
The NX uses 12V min, so how exactly does this work?
mau, both Jetson Nano module and Jetson Xavier NX module have 5V power input. See the module data sheets. Carrier boards are responsible for taking their power input and converting to appropriate spec for Jetson module.
Could you please clarify regarding this statement?

In the guide it says
