Hi,
It's small thing but may be i'm missing something.
I've got a new PCA10028 board and it works fine with Micro USB cable, I need to use it's Coin cell battery as well but it doesn't start (cause LED5 doesn't blink).
I'v tried to change the sides of the battery. Right now, it is placed like that the + sign of the battery is visible. Is there any Jumpler setting for this, User Guide doesn't talk about it ???
