the one that is brown.
the blue one is on one transistor, it will warm up and burn (IвЂ™ve so worn a couple).
in brown - the bottom row of resistors (from left to right) - 4 pcs. This is the switching of YUSB signals for different devices (Apple, Samsung, NTS). R2, R4, R7, R8
the following two resistors are the choice of voltage.
in the diagram it is R3 and R6.
their relationship can be played and get the voltage up to 12 volts.
VOUT = (R3 / R6 +1) * 0.6
really why set up? they come with an output voltage of 5.2 ... 5.4 V, so everything is fine.
and its input is from 0.9 to 5 - just LiIo battery (3.7v).
so if you don't need any special stress, then just buy and turn it on.Post has been editedKarl-Ieronim - 04.01.15, 15:02
