What you’re describing with the microSD card is definitely not normal. I’ve encountered it only a few other times in over 1000 boards, and it’s usually caused by a bent pin inside the microSD socket that causes a short circuit when a card is inserted. Is this a brand new board? And are you seeing this behavior with the microSD socket that’s built into the Mayfly, or with the supplemental vertical microSD card adapter board (that comes with the starter kit) that plugs into the 8-pin SPI header between the power switch and the D21 pushbutton? And do you see this same behavior with various microSD cards, or just one? Sometimes a malfunctioning microSD card will cause the problem instead of the socket itself.
