  • I would really appreciate someone’s assistance for a quick question. I am confused by the description for this item, it says, the board needs to be powered from the two voltage sources.

    I have a 3 volt circuit on one wire. At this time, it count on 1.5 volts or higher.

    Would this item help me bring the voltage above 2 volts on a positive count? Should I use another item to accomplish this,..

No public wish lists :(
