Hi， DC 12V 5.5A can supply Xavier devkit？
Yes, Xavier DevKit support voltages from 9 to20V. 12V/5.5A will result in 65W which is the same as the priginal DevKit power supply delivers.
what about xavier 32GB ddr Version? it’s the same ?
The support guide of my Xavier DevKit 32GB says under section “power rating”: 9V DC:10A ~20V DC:4.5A, and it was shipped with a power supply that delivers 19V DC:3.42A (65W) on the output.
