The Intel Braswell family of SoCs used on SBC-A80-eNUC board can manage up to four USB SuperSpeed (i.e., USB 3.0 compliant) ports and five High Speed
(i.e. USB 2.0 compliant) ports. There is only one dedicated High Speed port, the other four ports are shared with the SuperSpeed ports, i.e. they can be used
either by USB 2.0 or USB 3.0.

The USB 3.0 ports #0 and #1 are available on two single USB connectors, CN12 and
CN13, placed on the two opposite sides of the PCB ("Rear" and "Frontal", considering a
possible application of this board with an enclosure). The connectors used are two

Managed by the xHCI Controller, there are also two additional USB 2.0 ports, which are
hosted on a 9-pin p2.54mm pin headers ,h= 6mm, type NELTRON p/n 2213S-10G-E9 or
equivalent, with the pinout shown in the tables on the left (it is a common pinout for USB

For the connection of standard devices to this pin headers, it is needed an adapter cable. SECO can
optionally provide for such an adapter cable, as a part of the accessory kit p/n CABKITA80 (please check
