The signal mappings are as per the table above. All the signals are referred by the pin-no in the
SDK and the table above shows the default mappings. Note that some of the pins are repeated
across the connector. For e.g. pin 62 is available on P1 and P4, but only P1 is connected by
default. The signal on P4 is marked with a *(star) to signify that is not connected by default. It
can be routed to the pin by using a 0 Ohm resistor in the path. Please refer to the schematics
and placement diagram for the exact resistor placement.
2.3 Power
The Launchpad is designed to work from the USB provided power supply as it
enumerates as a bus-powered device. Care has been taken in the design to ensure that
the board does not violate the in-rush limits of the USB bus. The board can also be
powered by an external 2xAA or 2xAAA battery which is connected on J20.
