USB Client (X10)
With nanoETXexpress a new function called USB Client is coming up. If supported by the used chipset on
the module, USB Port7 is used as an USB Client connection via MiniUSB connector TypeA (X10). The
client function is a software implemented USB device in the chipset which allows connecting the
platform to other USB Host interfaces for purposes of file transfer, network connectivity or any other
USB functions.
