Serial cable to connect different OpenPilot peripherals.  All serial ports within the OpenPilot project use the same pin-out and the same connector, which this cable mates with perfectly.

The following boards have this standard serial connection:

• FOSS JTAG
• CopterControl ad CopterControl3D
• OpenPilot Revolution
• OpenPilot OSD
• OpenPilot GPS
• OpenPilot PipXtreme Modem

This cable is also used to connect a Spektrum Satellite or Futaba S.bus to the serial port on CopterControl.
