I am having a problem finding a Li-Po charger circuit like Benson uses in the diagrams upthread . Anyone have any good ideas?
Would some USB to 3.7v battery charger be good?
What voltage comes out of the Palm Touchstone module, I assume near 5v? How much amperage will it supply?
User Benson has gone the way of many TMO users since 2011 so I can't ask him.
