This port is intended mainly to provide an option for people who use ModXo as a debugging tool. The rear port is useful to avoid having to use the BSX front panel to hook up to USB for SuperIO debugging. You can plug into the port in the rear and open up windbg when your port gets enumerated. The included 3D print allows for you to mount the PCB in the rear and lock it firmly in place, assuring that you have a solid connection. You can also use the bootsel button on the BSX front panel to flash the chip using this port.
Thanks to Matty Suds and Aqua for their elemental help with this project. Could not have done it without them.
