This is a very simple board that takes a 6-12V input voltage and outputs a selectable 5V or 3.3V regulated voltage. All headers are 0.1" pitch for simple insertion into a breadboard.
Input power can be supplied to either the DC barrel jack or the two pin header labeled + and -. Output power is supplied to the pins labeled GND and VCC. Board has both an On/Off switch and a voltage select switch (3.3V/5V).
The two pairs of GND and VCC holes are spaced such that when connected to our Basic Breadboard both power busses will be powered.

Note: Headers are not supplied. You will need to supply your own headers to connect this board to a breadboard. Check below for some breakaway header strips.
Note: We’ve released a new version of the SparkFun Breadboard Power Supply Stick, it can be found here! The new version functions the exact same way as this older model but we’ve made a few changes to footprints, the silkscreen, and added a second set of pins that output to the breadboard to help with stabilization. Go check it out!
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: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

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.

I soldered the headers onto the power supply PCB, connected a 12VDC power cube to the power jack and it worked. A person can’t ask for any more than that…
What I really like about this proto-board design is that, the headers are correctly placed and allow for the power buss in each side of the proto-board to receive power.
This proto-board power supply is well worth the money.
Very sturdy and reliable - not cheaply made. And if you want it to sit flat and stable just connect it about 5 spots in from the edge and put a dummy female header somewhere under the other side.
I like the ideas behind the updated version for stability. Sparkfun makes it a habit of building their boards rugged and well thought out. This product is no different, it will do you well.
