we now have nRF52840 DK PCA 10056 , V3.0.0 . the documentation of product specification user guide available online is for v1.0 (old dk) , but not for v3.0 . please can you give me the link where to find this document online . previously we were using nRF52840 DK PCA10056 , v1.0.0 ,(used a lot many times ), now not working due to the failed to flash code on this DK . since there is no much difference between the two versions of board there are few pin changes like GND_detect on P19 (v1.0) present is absent in v3.0 PCA10056 nRF52840dk . thanks in advance
