Connecting to a Launchpad

The CC3100 Booster pack can be directly connected to a compatible Launchpad using the
standard 2x20 pin connectors. The jumper settings needed for this connection is the same as
that needed for the FTDI Debug board as described in the previous section.
Please ensure that the Pin1 of the 2x20 pins are aligned correctly before mating. The mated
setup is as per the picture below. (Note the USB cable is connected to the Booster Pack
directly to power it only. For debugging, the USB cable on the Launchpad is also required)

5.1 Launchpad current limitation

Some of the launchpads including the MSP430FRAM launchpads do not provide enough
current to power the CC3100 booster pack. The booster pack can consume upto 400mA
peak from the 3.3V and hence it may be needed to power is separately.
For this a USB connector is provided on the Booster Pack to provide the 3.3V separately.
The power supply jumpers shall be configured as below when the power is supplied from the
on-board USB connector.
