NOTE: All signals are 3.3-V CMOS 400-mA logic levels, and are referred w.r.t. CC3100MOD IC.
For example, UART1_TX is an output from the CC3100MOD. For the SPI lines, the
CC3100MOD always acts like a slave.

Power

The board is designed to accept power from a connected LaunchPad or from the CC3100EMUBOOST
board. Some of the LaunchPads are not capable of sourcing the peak current requirements of Wi-Fi. In
this case, the USB connector on the CC3100MODBOOST can be used to aid the peak current. The use of
Schottky diodes ensure that the load sharing occurs between the USB connectors on the LaunchPad and
the BoosterPack without any board modifications.
The 3.3-V power can also be sourced from the LaunchPad, or from the 3.3-V LDO on the board by using
jumper J8. If the LaunchPad is not able to source the 3.3 V up to 350 mA, configure the J8 to work from
the on-board LDO.
2.4.1 Power From the LaunchPad or CC3100EMUBOOST
The most common scenario is to power the CC3100MODBOOST from the connected LaunchPad. In this
case, the LaunchPad provides 3.3 V to the BoosterPack for its operation (see
3.3 V, some LaunchPads provide a 5 V from the USB (see
BoosterPack. If the LaunchPad is not able to provide the 5 V (for example, the LaunchPad with only 20
pins), then the USB connector on the CC3100MODBOOST should be used to provide the LDO input as
shown below.
