Connecting to a Launchpad

The CC3100MOD 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 EMUBOOST 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)

4.1 Launchpad current limitation

Some of the launchpads including the MSP430FRAM launchpads do not provide enough
current to power the CC3100MOD 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.
Important: Since there are two power sources in this setup it is important to follow the power-up
sequence.
Note : Always power the Booster Pack before powering the Launchpad. Failure to follow this
sequence may end up damaging the booster-pack permanently.
