Janus
Janus is an Interposer board with USB-Serial console access. This board sits inline between an Overo COM and Stagecoach, Pinto-TH, Thumbo, or Tobi Duo expansion board to provide USB console port for accessing the Overo COM.
Janus
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.
