3x USB 2.0 and 1x USB 3.0

Hello,

I’m new to Jetson Nano, so I’d like to confirm something that may be trivial:

  1. The Jetson Nano has 3x USB 2.0 ports and 1x USB 3.0 port, is that correct?

  2. If I want 3x USB 2.0 connectors on my board, I can simply route the USB0_D+ / USB0_D- pins to USB connector 1, USB1_D+ / USB1_D- pins to USB connector 2 and USB2_D+ / USB2_D- pins to USB connector 3?

  3. If I want more than 1 USB 3.0 on my board, I have to use a USB HUB IC on the USB 3.0 port, is that correct?

Thanks very much for your help!
Ed

Yes as you said.

For more info please refer to Jetson Nano Product Design Guide in DLC.

Thanks for your help. One last question: I see that the Jetson Nano schematics uses the TPS259530DSG IC (Electronic fuse and protection) to provide 5V to the USB’s VBUS pins. I assume it’s just an additional protection against faulty USB devices plugged into the Jetson Nano, and that it’s not really mandatory. Is that correct? Is it ok if I simply route my board’s 5V to the USB’s VBUS pins? Or that’s not recommended?

Thanks again,
Ed

TPS259530DSG is a load switch for VBUS which is recommended as you can see in Design Guide.
