SparkFun will be closed Nov 26th and 27th for the Thanksgiving holiday. Orders placed after 2:00pm MT on the 25th will ship out Monday the 30th.
Description: Your first exposure to electrical engineering - the bread board. Who knew it would bring so much frustration?
This is your standard solderless breadboard - three binding posts, two power buses, black aluminum plate backing. It works with a wide variety of wire gauges (29-20 AWG).
Check out our Unregulated Power Supply Tutorial!
Note: The power rails are unbroken on both sides.

First thing I did was try stick the rubber feet on and the adhesive backing didn’t stick to any of the rubber feet, so that didn’t work.
Then came the biggest issue. From one side of the power rail to the other, I measured 5 ohms of resistance. That’s not much, but think if you’re running a device that’s powered by 3.3V, minimum voltage is 3.15V, and it pulls 150 mA. With the 5 ohm resistance, that equates to a a 750 mV drop, which doesn’t work. I also had a lot of intermittent connection issues with the normal breadboard rows which caused my circuit to act strangely.
I thought maybe I got a bad one, so I tried the second one out. Feet didn’t stick, 3 ohms of resistance on this one’s power rail.
I’m sorry Sparkfun, but these things are junk!
2/2 failure rate for me.

College gave me some pretty bad breadboards to use. This changed all that.
The power rails are great for dedicated power setups, and the bread board itself is fairly high quality. I still have a couple designs stuck to it that I will return to when I have time. (I did some moving between this purchase and now, and the parts are still on it!).
This is a MUST HAVE for anyone that is doing electronics as a hobby. (I even used this to as the platform to program a few ATTiny85’s).
This was my first purchase with your company so to me it kind of sets a standard for the future. my experience with this product is such, so far . When I opened the package the breadboard was on the bottom of the box with the other few items that I purchased. When I lifted the breadboard package out it was immediately obvious that it had been returned by someone else,the plastic sealing had been opened and the cardboard backing was tattered.Upon further inspection i could see the reason why it was returned. The aluminum plate backing was bent in several places, not really bad, but enough to warrant this a second, not a first like I had been expecting. I straightened it out and will keep it and hopefully the damage won’t effect the usefulness of the product.
So my first purchase left me a little under enthused with Sparkfuns QC .
An update to my previous post; The Monday after the Friday that I posted my concerns about this product, Timothy from Sparkfun e-mailed me about my experience. He voiced his concerns about my purchase and wrote that a new board would be on the way to me post haste,,,, I have to say that I wasn’t expecting that kind of a response so soon,, so thank you very much Timothy and Sparkfun.
So here is the thing,,,,, when I got the new board I opened the box as before and found pretty much the same condition,,,, the board had broken free from its packing and the bits and pcs were strewn about.(but not bent) So it’s looking like the travel has taken its toll on the board and not a case of negligence at the Sparkfun end,,,, at least thats my story and Im gonna stick with it. Thank you again Timothy and every one at Sparkfun. I would recommend this product based on its cost,,, maybe not the best but descent value for the dollar and the support at Sparkfun was pretty awesome.
Feet didn’t stick. Posts were hard to assemble. Would have been better off buying the component pieces and mounting it to a scrap piece of plastic or similar.
The larger size (length) allows more complex test circuits to be assembled without tying in an additional board. Also I like the metal backing because of the added weight and larger footprint which makes poking in jumper wires and various other components/connectors easier. I have not use the power connectors, suppose they would be nice if you are using a large external power source. I use one of the breadboard power supply (obtainable from Sparkfun) for power hungry components which powers both rails and is switchable between 3,3V and 5.0V.
