A very simple breadboard power supply kit that takes power from any USB port and outputs a fuse protected and regulated 3.3V. The .1" headers are mounted on the bottom of the PCB for simple insertion into a breadboard. Pins labeled 5V/GND 3.3V/GND plug directly into the power lines.
When you plug this board into a breadboard you must be aware that the unused power and ground pins will short if they are inserted into a bread board row. To avoid this problem, orient the board so that the unused power pins are left off the side of the breadboard. You can also orient the board sideways and utilize both 5V and 3.3V at the same time.
USB v2.0 specifies a max of 500mA at 5V. The on-board fuse limits the current to 500mA. Board has a handy On/Off switch.
Comes as a bag of parts kit and is easily assembled if you can follow the silkscreen indicators and have beginning experience with a soldering iron. You will need to read the resistor bands or use a multimeter to determine the resistor sizes.

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

made a mistake by buying unsoldered version (they have a soldered one). now I need to spend time to read resistor bands, find where to place them, solder, etc… Thought it will be fun, but it just do not worth time… Next time will buy a ready to go one :-) Moreover I found that I do not need this particular board, what I thought when I was buying it, I do not know… The rest is good, received it on time, all parts are in bags, just need some time to make it ready…
