Can the UART on this board be used for external flight controllers? It looks like its using the QUP13 UART but the M0125 board uses GPIO_22_UART7 on  /dev/ttyHS1.

@tom Oh totally missed that, thanks! Also, do  you know if when using that board, one USB can be used for an ethernet adapter and the other can be used for UVC Cameras?
