    Have you seen the pin out information on the mDot’s mbed platform page? I think that has what you need.

    What should be the communication tool/software to be used and input voltage 3.5V is enough? We tried with 3.5 to 5V supply and docklight tool, but we are unable to get response form mDot board without development board.

    Do you have an mDot Developer Kit? That UDK is needed for programming the mDot because the required ST Link circuitry is on the UDK itself. Plus, the UDK will give you a DB9 connector for easy access to the AT Command port.
