2.3 Power

The board is designed to accept power from a connected LaunchPad kit. Some LaunchPad kits cannot source the peak current requirements for Wi-Fi, which can be as high as 500mA. In such cases, the USB connector (J7) on the BP-CC3351 can be used to aid in extra current. The use of Schottky diodes make sure that load sharing occurs between the USB connectors on the LaunchPad kit and the BoosterPack module without any board modifications. The jumpers labeled J6 (1.8V) and J8 (3.3V) can be used to measure the total current consumption of the board from the onboard LDO.
