This seems tricky. Is there documentation for this cycle change? Unless there is a switch, isn't there a possibility that it will run slower and overheat?
You need a DC adapter that is compatible with the region you live in, yes. The board itself is the same. I gave 2 boards that I bought in Europe away to friends in the US, there are no problems; they just needed to get the correct adapter.
