So now dblejeune just needs to use a LED-Resistor calculator to limit the current (and thus drop the voltage)and hope that works.
There are other pages on this site, other than the forum, you know. One, quite easily to get at from the front page, "Products" show the basic specifications: 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.
