Another picture to help with the DC-DC buck converter addition.
Magenta is ground (or negative pole) shared between input and output (and everything else; negatives are connected also on the buck converter if you look carefully on the back). You have different options as to where to solder your little cables.
-
Cyan is input positive (18V or 5V or whatever, I don't know).
+
Cyan is input positive (18V more or less).
-
Yellow is output positive (to set to 3.3V)
+
Yellow is output positive (to set to 3.3V +/-10%)
I removed the troublemaker chip first with a good knife, cutting vertically all the 8 pins. Then I used some precision pliers to rotate it back and forth and it came off quite easily.
I'll solder the buck thingy as soon as Jeff B. ships me the tools and stuff needed for this job, which incidentally brought me into electronics as a new "hobby".
