DCA1000EVM连接5V/3A的电源后,电源5VLED灯的一闪一闪的微弱灯光,并不能保持常亮,应该是供电不正常,请问该怎么解决呢
我一般都是双电源供电的。
如果您需要单电源供电的话,请看一下IWR1843BOOST板子上J1处的r34电阻是否有焊上去?
请看一下DCA1000EVM板user guide上的说明Table 1. Power Selection Switch Information。
When the switch is closed to position 3, then the 5-V power is derived from the xWR1xxx EVM through the 60-pin connectors.
Note: To get 5-V power from the xWR1xxx EVM, the R34 (0 Ω) resistor should be mounted in the xWR1xxx EVM.
