Max current supplied by TX2 Dev board on USB ports?

What are the specifications for dev board on the max amount of current supplied to the USB ports? Is it shared or each port has a separate isolated power source? Can it be changed/increased like for example on Raspberry Pi boards?


Hi albertr,

You can refer to the datasheet of load switch, APL3511CBI-TRG, which maximum output is 1A and can’t be changed.

Thanks! I assume it’s shared by all USB ports?


No, USB2.0 and USB3.0 both have their own load switch, you can check the schematic for this.

Great, thanks!
