I am looking to get a PCB board which has 100 usb2.0 or usb3.0 ports.
This can include powering arduinos, raspberry pies. Also I need to be able to read/write to harddrives. Or any mixture of the above.
How can I go designing a PCB that can do this? Some research I have done: 1- Good power supply that can supply 2A per port. 2- Usb chip that can be used efficiently. Any insight would be appreciated.
