    May design for arduino then not match with my bread board.

    Very nice and handy bread board PSU. The small size will allow you to use the complete bread board. The lower pair of connectors supply the 5 voltage, and the upper pair can be switched between 5 and 3,3 volt. One small problem, the size of my bread board supply lines are different than the PSU board. A small adapter will solve this problem. Thanks for the prompt delivery!

    but have not tested yet. the quality of the boards seems higher - the board is clean and solder joints of the one i looked at seem solid - than i have received from other vendors. however, the individual anti-static bags are not well labeled - just a few different stock numbers and no description/specifics of the item in the bag.

    After damaging my original power supply (I accidentally connected a 15v supply). I ended up ordering 4 more, as they are so useful. Now my kids can make their own electronics projects without borrowing my supply. The input voltage (max ~12v) feeds the 5v regulator, which then feeds the 3.3v regulator. The lower pair of connections supply 5v, and the upper pair can be switched between 5v and 3.3v. It works well from a USB supply, although the 5v supply might be a bit under 5v, depending how well regulated

    I received my first order from BangGood, including four of these power supplies. Two of them had significant solder problems. On the first, Capacitor C2 had only one leg solidly soldered down, and the capacitor was bent at a dangerous angle from the motherboard. It's fixable, and I will probably fix it, but I am concerned about other joints I can't see. The solder joints on the other were cold joints with heavy flux contamination and pitting. I'm not certain this one can be fixed, but I'll give

    works with USB or 12v input. One output Vcc is 5v the other can be switched between 3.3v and 5v. Shows economy of design with the one switch and good small footprint.

    So good, I bought a whole collection.
