The Janus™ expansion board sits inline between an Overo COM (or Overo STORM
series COM) and a Stagecoach, Pinto, Thumbo or Tobi Duo expansion board, and
provides a Serial-over-USB port for accessing the Overo COM console.
With a footprint very close to the Overo COM (the USB connector sits
vertically outside the COM footprint), the Janus board can be used to debug
many expansion board settings where a console port on the expansion board has
not been configured.
