CC3200Launchxl和CC3200AudioBoosterPad组合供电问题

CC3200Launchxl和CC3200AudioBoosterPack组合供电问题:

1.若通过PC机的USB供电,直接给CC3200Launchx板子供电,而CC3200AudioBoosterPack板子从CC3200Launchx板子引电,可否?

2.若电池供电,可否直接用一节锂电池(3.7V供电)?

3. .若电池供电,2*AA电池供电,即是3V供电吗?系统板不是要工作在3.3V电压吗?

Viki Shi:

No on-board LDO. Once the CC3200AUDBOOST and the CC3200-LAUNCHXL are connected, the CC3200-LAUNCHXL sources power to the CC3200AUDBOOST. Specifically, the CC3200-LAUNCHXL provides power to the audio codec and the power amplifier on the CC3200AUDBOOST

回复 user5291030:

需要两节AA电池供电,3v也是可以的【 Can be powered externally, with 2xAA or 2xAAA alkaline batteries working down to 2.3V typical (typ).】

user5291030:

CC3200Launchxl和CC3200AudioBoosterPack若外部供电,除了用2节AA电池,可否直接用锂电池供电?

Viki Shi:

回复 user5291030:

CC3200一般推荐的电压范围是 2.1 to 3.6 V,实在要用的话,3.7v接到J20上
