LaunchPad Current Limitation
Some of the LaunchPads, including the MSP430FRAM, do not provide enough current to power the
CC3100 BoosterPack. The BoosterPack can consume up to 400 mA peak from the 3.3 V and it may be
needed to power is separately.
For this, a USB connector is provided on the BoosterPack to provide the 3.3 V separately.
The power supply jumpers should be configured as shown in
when the power is supplied from
the on-board USB connector.

NOTE:
Since there are two power sources in this setup, it is important to follow the power-up
sequence.
NOTE:
Always power the BoosterPack before powering the LaunchPad.
