The power supply is perfect, there are two switches with which you can select the output of 3.3v or 5v. in input the board can be powered with miniusb connector or with 7v-12v plug. there is a led to mark if the board is properly powered. There are various outputs that interface directly with the breadboard or can be used with wires and DuPont. I checked the outputs with a voltmeter and are perfect.
This is a very smart circuit. I've been always struggling with power supplies and wires, but this addition to the breadboard makes everything more easy. Due to the onboard voltage regulators, you can choose between the 5 V and 3.3 V voltages, so you can drive different digital circuits easily. The voltages can be selected per rail (so, you can have one side at 5 V and the other at 3.3 V. There are 2 switches for it. You can power the board with an external PSU or USB (microusb).
Reasonable price, bought to replace that of a kit that broke in shipping, did not test
