CC3200STK-WIFIMK: Can CC3200STK-WIFIMK be connected to a 5 Volt DC power supply?

Other Parts Discussed in Thread: CC3200

Since the battery life of CC3200STK-WIFIMK is short, can it be connected to a 5 Volt DC power supply?
Is there any method to extend the battery life of CC3200STK-WIFIMK?

    Chung,

    A voltage regulator is not provided at the battery interface. There is one on the DevPack connected to the USB port, but I recommend that you use 2 AAA batteries and power the SensorTag with 3V as it was designed for.

    The CC3200, external flash, LEDs, buttons, and 7 sensors are all being powered from the batteries. To extend battery life, you can make hardware modifications like depopulating or cutting power to components that I can afford to lose to lower power consumption.

    Additionally, the SensorTag is a demonstration platform and not for development. I recommend the CC3220SF LaunchPad and Sensors BoosterPack for development where you can test low power modes.

    Seong,

    Thank you so much.

    So does it mean I can use a power bank to provide power supply to my CC3200 through the USB port?

    BR,

    Yes, you can safely power the CC3200 LaunchPad with a 5V power bank connected to the USB port. There is an LDO (TPS79601) interfaced with the USB that sources 3.3V to the CC3200 device and other components on the board.
