I am waiting for a Nano but am a little confused (as usual) about the power input. I would like to use one of those Breadboard Power Supply Modules 3.3V - 5V but the spec states an input voltage of 7-12V. I would have thought that %v would have been OK but I suppose it depends on the output load. The only other way for me would be a 12 supply if I could get it connected as there is no DC power jack. Any help for an old fogie would be appreciated.
