2.5.2 Battery Power (2 x 1.5 V)

The LaunchPad can also be powered from an external battery pack by feeding the voltage on the J20

header. This input features reverse voltage protection to ensure that the board is not damaged due to an

accidental reverse voltage. The following care should be taken while using the board with a battery

1. Remove the USB cable.

2. Plug-in the battery pack on J20 with correct polarity (see Figure 10).

2.5.3 BoosterPack Power Supply

The CC3200 LaunchPad can be powered by a stacked booster-pack which can provide a 3.3 V power on

P1.1. During this mode, ensure that the J13 is removed so that the on-board LDO is not overloaded.

2.6 Measure CC3200 Current Draw

To measure the current draw of the CC3200, use the 3V3 jumper on the jumper isolation block. (J12). The

current measured in this mode includes only the CC3200 current and no external blocks. However, if a

GPIO of the CC3200 is driving a high current load like LED, then that is also included in this

measurement.
