starting to get to some of the more useful things in the box, were this 6 DC-DC Step down converters, 4.5v to 40v in and 5v/2a out with a voltmeter.
But I have no idea why I needed 6 of these, I already have a few, but it's kind of mixed as when I use them.
@yougenius @synthdiy This is what I use, I could wish for another digit on the precision when matching transistors but really it's good enough #voltmeter #synthdiy
