I would fry all my projects with this thing – the variable output has -/+ switched and if one connects to the other rail as per breadboard colors – you get -2v… would rather have switches for voltage for each power rail (leave gnd as gnd).
will stick with mb102 :/

This is stupid beyond belief. How can anyone create such a bad design which ignores all breadboard conventions.

Meh. When someone puts an LP3906 or ACT8931 or other PMIC reference design onto a breakout board, I’ll buy half a dozen. Until then, I see nothing more than goofy branding for Makers and I wouldn’t pay $20 for it at any rate.
