3.1.10.2 BoosterPack Site 2 Power Isolation

JP8 is included to isolate 3.3 V and 5 V from the BoosterPack site 2 headers. This might be required if two BoosterPacks are simultaneously connected to the LaunchPad and both provide power to the LaunchPad. If this is the case, power can be isolated by removing the shunts on JP8 and there will be no contention between the two BoosterPacks.
