Power consumption - DWM3001C

[Braxatoris]

Hello guys,

Im developing RTLS with DWM3001C and right now Im working on personal tag powered by CR2450. So naturally, power consumption should be as low as possible.

So far I managed it to these levels - idle not moving - around 15-20 uA, after moving tag UWB TX is around 22-30 mA spike, and periodically there are every 100ms spikes of 60 uA +/- from accelerometer sampling.

Over past year, i tried everything possible but this is as low as it gets... from what i read it should be able to go 5 uA +/- ? 

Any help will be appreciated :)

Hi

Okay, do you have an nRF52 series development kit you can measure current on with this device just to make sure we have the same point of reference? For example the system OFF sample here running on a DK can make sure the measuring device is correct: https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/samples/boards/nordic/system_off/README.html#nrf_system_off 

Please upload what current consumption you see and what DK you're testing on. If this is expected/similar to what we see on the PPK we can move on to your board.

Best regards,

Simon
