I don’t think I’ll be putting this away in a box anytime soon. This board is quickly becoming a staple element when I’m working on a breadboard. The most useful feature is being able to have one side @5V while keeping the other side @3.3V, this board saves time because it’s a no-brainer. Not to mention highly versatile allowing supply from a dc jack or from mini-usb. The board I received differs from the picture shown in that mine is on a red pcb which I prefer. It also differs as mine has no jumpers to move or large on/off switches, they’ve been replaced with a pair of smd switches to select whether each side is on or off, and whether each side should be @ 5V or 3.3V. And as another reviewer mentioned the crescent shape of the board keeps the power supply from covering over any breadboard pins besides those in the power rail areas that it uses. Great quality as well and a very clean appearance.
