Power selection
The board can be powered from the USB connector using the on-board LDO (3.3V) or using an external battery (2xAA). The
battery is connected to J24. There is built-in reverse polarity protection for the battery connector.
The selection between the battery and USB power is performed using the jumper J23.

USB connections
The Launchpad features an USB connector labelled J25.
J25 is used to power the board and also for the JTAG emulation and UART ports. Currently only one UART port for the
flash programming is provided on the board. The board requires the installation of Stellaris ICDI Drivers to be installed for
proper operation. This is provided as part of the SDK release.
1.1.4
JTAGsignals
The JTAG lines are brought out on separate headers on the PCB. The jumpers are shorted to connect the CC3200 JTAG to
the ICDI device on-board. To use an external emulator, these jumpers have to be un-installed and the JTAG signals to be
connected on the jumpers below.
