LaunchPad™ Kit Current Limitation
Some of the LaunchPad™ kits, including the MSP430FRAM, do not provide enough current to power the
CC3135 BoosterPack™ module. The BoosterPack module can consume up to 400-mA peak current from
the 3.3 V, and may need to be powered separately. For this, a USB connector is provided on the
BoosterPack module to provide the 3.3 V separately.
The power supply jumpers (J7) should be configured, as shown in
, when the power is supplied
from the onboard USB connector.

CAUTION
Because two power sources exist in this setup, it is important to follow the
power-up sequence. Always power the BoosterPack™ module before powering
the LaunchPad™ kit.
