I have a question witch i cant find an answer on anywhere so i have to make this question.
As i can see the Spark Core is running on 3.3V DC.
Or can it also run on 5V as the Arduino ? When supporting the board without the USB power. On the GND and VCC connections.
Does that mean the I/O ports then only provides 3.3 V when they are set to High ?
And what about 5 V DC on input ports, will that damage it
Because now i use Arduino witch components requiring 5V, will that not be possible on the Spark Core ?
Or will i then need to have a 5V to 3.3V DC Converter to power the Spark Core and the normal components requiring 5V ?
