i’m thinking about vision deep learning with jetson nano

nano have 4 usb 3.0 ports,

so i’m going to connect HD USB camera(1920x1080) in all ports,

but i 'm not convince that mainboard in jetson nano will cover them.

how many webcam should be nano cover?

Hi,  
Please refer to

> Hi, With further investigation, we found bandwidth limitation is hit in using USB2(High-Speed) cameras. High-Speed limit is 480Mbps. In the [test](https://forums.developer.nvidia.com/t/deepstream4-jetson-nano-multiple-webcams-issue/79030/12), two E-Con See3CAM\_CU135 are USB3(Super-Speed) cameras. Please use USB3 cameras to get 5Gbps bandwidth.

The four ports are in embedded USB hub and share 5Gbps bandwidth. You would need to use USB3 cameras.
