Hi Björn,

That was useful guide for the pca10040 but what SBs should I cut in pca10056 to measure nRF52840's current only? As in pca10040 case I use the Otii device to supply power also for the pca10056 board. Since the Otii measures the current taken from the it's supply current I need to connect it to P21 (or perhaps to P22 as in pca10040 case?) to measure current and get rid of any extra current drained by other components on the board. The user's guide for pca10056 did not explain this kind of set-up clearly, Please guide me what shall I do.

Thanks.

Ari
