4 Port USB hub (X4 & X5)
The board comes with a total of 4 USB Type-A ports in connectors X4 and X5 (shown below)
facilitated by a USB hub controller that is connected to USB1 port of the processor. These ports
can be used to connect USB storage devices and other USB gadgets such as WiFi adapters
and wireless/wired keyboard and mouse. The 4 ports can supply a combined current of 500mA
to the devices that are connected to them when the board is powered through AC input. While
they cannot supply 500mA when the board is powered using the USB port of a laptop/computer,
low powered USB devices can still be used.
