Got a Due today, started playing with it, and put a custom shield on it that was designed to be powered by either 3v3 or 5V from the ICSP header. Assumed the Vcc on the ICSP header would be 3v3, so that's what I set the voltage selection jumper to on the shield. Just before I plugged it all in, I h…

5V where you might not expect it

Not sure why you were surprised - the Due schematic shows +5V on the SPI and ICSP headers.
There is no jumper/switch on the board to select a voltage that I have seen, is there?
