2.3 Connecting a BoosterPack
A compatible BoosterPack can be stacked on top of the LaunchPad using the 2x20 pin connectors. Note
that the connectors do not have a “key” to prevent the misalignment of the pins or reverse connection.
Ensure that the V
cc
and 5V pins are aligned with the BoosterPack header pins. On the CC3200MOD
LaunchPad, a small white triangle symbol is provided near Pin-1 (see Figure 3 ) to orient all BoosterPacks.
This same marking, provided on compatible BoosterPacks, must be aligned before powering up the
boards.

2.4 Jumpers, Switches and LEDs
2.4.1 JTAG Headers
The headers are provided on the board to isolate the CC3200MOD device from the mounted FTDI JTAG
emulator. These jumpers are shorted by default when the board is shipped from TI. To connect an
external emulator, remove these jumpers and place the external emulator on the pins closer to the
CC3200MOD device.
