Is it possible to put Segger IC to low-power mode on MDEK1001?

Hi,
We are building a battery-powered application based on MDEK devices and our custom firmware. We noticed that the board consumes in order of tens mA even when the DWM1001 module measured separately consumes sub-mA.

We suspect that it might be the Segger IC drawing that current, as its LED is constantly ON or blinking at a high rate. Is it possible to somehow put the Segger chip to a low-power mode when it is not used for debugging?

Best regards,
Timofei

Hi,
You will have to remove the power to the STM part. There are some jumpers that allow this and some threads on the forum that discuss this in detail. Schematics for the DWM1001-DEV are available to download.
Thanks,
Ken
