Serious problems in the testing of V3.4 version.  As the testing, the max current can be upto 2.5A when SIM808 powerup.. the 3.4 DC power circuit do not bears so big transient current, that make the SIM808 do not powered up .:-(.. although this circuit works with A9G, but SIM808 needs much bigger current...

So we update again , to the version 3.5, and slves this problem ultimately.
