Hello,

I have a question that sounds basic but I couldnt find the answer anywhere else.

Does the USB connector of the Arduino Mega output 5V when the board is powered through the VIN/ external connector/jack ?

Thanks in advance,

Cheers !

No. The MOSFET T1 is preventing that.

But there is a flaw, if you power the board via the 5V pin, there IS 5V on the USB socket and your PC does not like that ;)
