5.2.5 USB Full Speed
The USB C connection jack (J11) connects the Main MCU USB Full Speed interface to an external USB
interface, allowing communications for testing and use of the Main MCU firmware. This connection can be
configured as either a USB Device or a USB Host interface.
For a USB Device configuration, set Jumper J14 to pins 1-2, and configure the Main MCU firmware to use
the USB Full Speed ports in device mode. Power from an external USB Host on this connection can be used
to provide power to AIK-RA4E1.
