Power Supply Requirement

Our company is considering using multiple NCS in our product, but the power supply requirement seems a little vague. If we plug multiple sticks into a USB hub, is it correct to say that 5V&3A is required for each USB port in the hub?

Experience has shown that in the USB 2.0 mode, it is fully operational with 1 port = 5V

 

and 250 mA to 300 mA.

 

A self-powered USB hub is required.

 

It is not the maker official information.

 

It is the result of my experiment.

 

I use four at the same time and are moving normally.

I've noticed the stick consumes a peak of 2.5 watts. So you should allow that much per stick. The peaks are very short but you should provide headroom in case they happen to overlap.
