You can put a 3V LDO regulator on your board and run it that way, you should be able to read the VTG from the Dragon in programming mode. >I have the unit and I'd like to hook it up to a 3.0V circuit No problem I have worked with 3.3V circuit. The Dragon uses the VTG voltage from the target board to adjust the it's I/O level, in other words the target voltage can be anything from 1.8V to 5V and the Dragon should work.
