Hi guys,
I bought the sparkfun breakkout board (www.sparkfun.com/.../13990). I also have the NRF52 DK from Nordic. I programmed the breakout board via the DK over SWD. And I cut the power LED. My code is running on both (DK and Breakout) and they both get the same results, besides:
The current consumption on my breakout board has a steady offset of about 400uA @2.8V / 145uA @ 1.8V. (I got a power analizer and I'm quite sure, that it is a constant current)
On the DK, the current is about 4uA (and thats what I expect).
So any idea, where this difference is coming from?
S132, SDK 11, SD 2.0.1
Best regards
UPDATE: I solved the problem: Although I connected a power supply to 3V3 and not Vin, the on-board regulator caused the additional 400uA. I desoldered the regulator and now I'm getting my 4uA ;-)
