And perhaps change a resistor, or easier, piggyback a resistor, or easiest, put a resistor in the 5V->3.3V selector jumper holes, in order to yield a custom output voltage like 6V or 8.5V?
Unfortunately, that design cannot output above 5 V. We have some newer products in development that should be able to step-down to 6 and 8.5V. They should be available very soon (probably before the end of the year).
