What happens if both vin and USB are connected to 5V

Hardware

I am wondering what happens if I connect the vin to a 5v DC and at the same time I connect the spark core with USB.

That’s not an issue since there’s a protection diode from Vin to VUSB :smile:

@helxsz, there is a protection diode which isolates the two sources so it is safe to do so. :smile:
