AWR2243: AWR2243级联板需要什么供电标准

Part Number: AWR2243


AWR2243级联板+TDA2XX采集卡,需要什么供电标准

  • 供电标准是12V 5A Power supply,请参考mmwave_studio_03_00_00_14\docs\mmwave_studio_cascade_user_guide.pdf文档2. Hardware Pre-requisites

  • 但是,《采用级联毫米波传感器的成像雷达参考设计》文档中提到,

    The Cascade RF board accepts 5V DC, 8 A (max) power through the host board connectors. The primary

    5 V system rail can be converted into the various AWR2243 device rails by a pair of LP87524P, quad

    channel, monolithic, buck-converters

    以哪个为准呢。目前我们用5V的电源,雷达也能正常工作。

    另外,想问一下有没有推荐的电源,我们这边想买一个。

  • 上面文档中提到的5v是级联板的电源要求。这个5V是由TDA2XX采集卡转换提供的。所以只需要给TDA2XX采集卡提供12v 5A的电源即可。可以看一下级联板的文档说明。

    只要能提供12v 5A电源适配器都可以,TDA2采集板文档中列出的是advantech的适配器型号。
    The typical power source is 12-V, 5-A Advantech Power supply P/N: 96PSA-A60W12V1-1.
