It has an 1117S 3.3 voltage regulator right behind the power plug, and the datasheet says up to 18 volts is ok. Can I trust that? There is a PJ52 S614 diode before the regulator also, and several capacitors. The only info I can't find is the manufactorer to ask about the correct power supply voltage. I was going to try a nine volt 500mah supply but decided to ask first.
