USB Ports interface[edit | edit source]

Description[edit | edit source]

The Evaluation Kit provides two USB3.0 ports at the connectors J3 and J4.

J3 and J4 are USB Type-C connectors. J3(right side on the image) is also used to supply the system, see Power Supply section.

Both ports can provide 5V output up to 2.2A. J3 port can also be configured to provide up to 3.3A

Device usage[edit | edit source]

The USB ports can be used under Linux for connecting USB devices: the related device driver has to be integrated into the Linux kernel.

To connect USB devices to J3 an USB-C HUB has to be used for power the Evaluation Kit while transferring USB data. Please check that the chosen HUB is qualified for the Power Delivery protocol.
