Now i am using the oscilloscope. I don&#39;t know why flow the current.

If it was, could you redo the measurements with the USB disconnected, but with a coin cell battery in the battery holder? This would eliminate any noise from the USB, and the coin cell would allow to see if there is leakage.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/102689?ContentTypeID=1Wed, 18 Oct 2017 15:45:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5539558f-afe2-4b00-969e-a0274c743649Kaito<p>thank you for your reply!!
