Jetson Nano Developer Kit

0. [J48] Power Select Header:

   Not Connect= USB Power

   Connect = Barrel Jack Power 

1. [J28] USB micro B, 5V 2A

2. [J25] Power jack, 5V 4A (The maximum supported continuous current is 4.4A.) 

 

** The critical point is that the Jetson Nano module requires a minimum of 4.75V to operate.

** Adafruit’s GEO151UB-6025 Power Supply (validated by NVIDIA for use with the Jetson Nano Developer Kit) is designed to provide 5.25V

-> some Micro-USB power supplies are designed to output slightly more than 5V to account for voltage loss across the cable

 

** The carrier board consumes between 0.5W (at 2A) and 1.25W (at 4A) with no peripherals attached.

** The default mode provides a 10W power budget for the modules, and the other, a 5W budget.
