DCA1000EVM: The AWR1843BOOST and DCA1000 data acquisition card were wrongly connected using a 12.6V1000mA power supply.

Part Number: DCA1000EVM
Other Parts Discussed in Thread: AWR1843BOOST

The AWR1843BOOST and DCA1000 data acquisition card were wrongly connected using a 12.6V1000mA power supply

When used incorrectly again, it was found that a row of red lights lit up in the upper left corner of the DCA1000. After replacing it with a normal power supply, the data acquisition work could not be carried out normally using mmwave studio. The main issue is that it cannot connect to the DCA1000, which shows

Could it be that the DCA1000 was burned out due to excessive power supply voltage?

But I can use the demo visulizer normally.

  • Yes, probably the DCA1000 was damaged by the 12V power supply.

    thank you

  • Hi
    Cesar
    So, is there a way to determine which part cannot be used?
    Or, could you offer repair services?
    thanks

  • I initially used the wrong power cord, which was powered on through the AWR18443boost. So, will the 1843boost also be affected?

    But I tested using demo visualizer and got results.

    In addition, I found that when I used the power cord (normal 5V 3A) to supply power through the DCA1000 and correctly adjusted the position of the power jumper, the serial port of the AWR1843BOOST could not be read at this time, as shown in the following figure.

    And at this moment, there is a red light on the radar board


    One last point to add is that the two lights below are always on. I don't know what they mean

    Looking forward to receiving your reply

    thank you



  • Hi,

    Based on your evaluation, it seems that the AWR1843BOOST board works fine.

    We don't offer repair services. 

    The schematics are provided. You should find some local repair shop to look at it.

    Thank you
