Description: Description: This is one giant solderless breadboard! It has 7 power buses, 40 columns, and 63 rows - with a total of 3220 tie in points. All pins are spaced by a standard 0.1". The two sets of five columns are separated by about 0.3", perfect for straddling a DIP package over. The board accepts wire sizes in the range of 20-29AWG.
This board also has 4 binding posts, a black aluminum plate backing, and 4 rubber standoffs to keep your breadboard suspended safely on your workstation.
Dimensions: 9.25 x 8.0 x 1.25" (234.95 x 203.2 x 31.75mm)

It’s hard to get excited about a giant breadboard, but it is exactly what it says it is: a giant breadboard with screw terminals. I can’t think of anything to say about it other than that, which I suppose is the best compliment I can give. :)
Love my giant breadboard. As someone already mentioned in a separate review, the rubber feet do not adhere very well to the bottom of the board. This could be a problem if you use the binding posts, because without the rubber feet, the binding posts will contact the bench, and you risk a short. Probably best to avoid the binding posts. Fortunately, they can be easily removed by unscrewing the nut fasteners. Alternatively, you could find better feet.
But for the rubber legs that won’t stay glued to the back of the board, but who would seriously expect those things to stick to the metal more than a day or two anyway?
This is a great product. It has a fantastic build quality. I will mention that I opted to use my own adhesive bumper feet, which had a larger adhesive base than the feet provided, after reading the issues people had with them. Feet aside, this is definitely going to help me with larger projects, or organizing multiple smaller projects on the same board.
So far this thing is great… what isnt to love about a nice and roomy, 4 large breadboard wide breadboard :) Tons of room for mucking around with guitar distortion circuits. And the price is no more than 4 large breadboards sold individually! (I believe I got mine for a little less than buying 4 boards individually.)
I was super excited to finally have room to do larger prototypes. Unfortunately, the tie in points are very inconsistent in what diameter wire they accept. Don’t expect to use this product with the resistors that are in the SparkFun resistor kit. If you turn the breadboard over, half of your resistors will fall out. This makes testing a nightmare and the board untrustable.
I have one of these on m desk that I just turn upside down and shook, and I can’t get anything to fall out. Sounds like your’s may be an anomaly. We’ll take care of that for you.
Fantastic price, worth getting more than one. The big distributors (Mouser, etc.) don’t seem to give you breaks on prototyping stuff, so this is the best price around. Not even Amazon sellers have something comparable.
Just to share: I don’t usually use the binding posts, so I’ve been using the empty space on the metal for mini-breadboards and euro-style terminal strips.
My design workflow is so much better with a couple of these sketchpads on my bench. Thank you, Sparkfun.
Excellent product, I’ll recommend it.
The contacts are a little tight when poking leads in. Resistors & capacitors and even #22 solid wires may buckle unless you poke them in with needle nose pliers near the end. BUT, it’s not all that bad.
Really, this is an excellent value for the money. I have two now and will probably get a couple more so I can set unfinished projects aside. I just pull the banana patch cables from the binding posts and swap the other board in. At this price, it’s affordable to do that.
The size, orientation and number of tie points is just about perfect in my opinion.
One other minor caution; the rubber feet tend to discolor blue antistatic mats over time. They leave permanent brown spots. I suspect a slow chemical reaction. I pitched the feet and attached a few layers of non-slip, self-adhesive strips (from Home Depot or Lowe’s) to the bottom along the edge with the binding posts. These don’t react with the mat, the board stays put, the binding posts are kept away from the mat and the board tilts toward me just slightly. Life is good. :-)
