Measuring power consumption on DWM3001CDK Board

How I do measuring the power consumption on DWM3001CDK Board?
I want only to measure the power consumption of the DWM3001 and not the On-Board debugger etc.


Hi @jul-nc
see the image below. You should be ok with disconnecting:

  • J16 - Segger power
  • J6 - Segger RST signal
  • J4 - disconnect the DWM from internal DCDC

And apply power (3v3V) to J2 (upper pin, blue arrow) and connect GND to J1 upper pin (yellow arrow).

But you need to take care bout GPIO output settings otherwise you would be able to to power up the Segger stuff via GPIO and that would cause unwanted leackage.
