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).

Note: The power rails are unbroken on both sides.

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).

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.
