I pulled this board from my portable speaker box. It originally powered an XM radio receiver. I get 6.1V from a 3pin plug on the right of the picture. I would like to use this plug to power a 5V plug to charge my iphone. I understand how to wire the plug after I have 5V through this plug. I should be able to change something on this board to get the 5V, instead of just adding another regulator or diode.
Can anyone help?
