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

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).】

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?

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
