Hi!

I know the voltage and current required by the device is 5V/2.5A. I use the power supply to connect jetson nano and iwr1443boost, and then jetson nano will not have power. So I want to know what the starting current of iwr1443boost.

  • Hello user6239141,

        Power number depends upon various chirping configuration and number of Tx and Rx used in the system.

    Most dominant power consumption in the EVM is mmWave sensor and PMIC. 

    Absolute maximum power consumption for each rail is given in the below table. 

    Typical use case power is provided in the below table. 

      

    There is also power estimation calculator depending upon the configuration from the below link.  https://www.ti.com/lit/zip/swrm018

       

    Thanks and regards,
