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)

Customer Comments

  • It would be cool to have an ATX connector on this board wired up to the power rows.

  • Just got mine. Looks like a good value, though I haven’t used it yet. A minor defect: The row and columns labels are misprinted. Each row of 5 tie points, where components would be inserted, has contradictory labels. At the top of the board, the columns are labeled A-J from right to left, while at the bottom of the board they are labeled A-J from left to right. Similarly, the top row of tie points is labeled 0 on the right side, but 60 on the left side. You can faintly see this from the product description photos.

  • Nice size, however a few basic problems that really need to be address. First, the holes for the binding posts are keyed. Flat spot in hole for a flat spot in the binding post to keep the post from turning when tightening. Only problem with this, is the holes are too large for the binding posts so they spin freely in the hole. Second is the rubber feet. They don’t stay stuck. I have had it only an hour and so far all of them have fallen off at least one. Will probably end up supergluing some new ones to the board so they stay in place. Or just take the binding posts off (not really going to use them) and put on shorter feet so they don’t catch on stuff and get knocked off like these longer ones do.

    • The binding posts do turn freely, but I cinched them down (tightly, but not TOO tightly) with a little wrench, and they’re solid.

      I do concur with the comment about the rubber feet–they don’t stay on. I’ll probably replace them with square adhesive-backed feet which have a lower profile and larger surface area. You should also prep the surface with a little isopropyl alcohol to remove any surface oils, etc. before applying the feet.

  • Decent product but there does seem to be a defect on mine. The upper left positive and negative rails are shorted together. Checked all the other rails and they seem fine. Be sure to check your boards for shorts before powering them up!

  • Question, I have an purchase on hold because this item is on backorder, the “We have a purchase for (so many) units….. etc. etc. etc. has been pushed back about three times since I made my order on 2014-02-18, just wondering if its because the items were all spoken for before they arrived or if the expected shipments for some reason didn’t arrive?

  • When is this coming back into stock? It say March 10 but that’s four days overdue!

  • While the size of this board is awesome, the foundation of it is simply inadequate. I found that if I press on the board I will get connections where there should be none, and no connection where there should be. I had a simple LED on the board being flashed by an Arduino as a test. I got no response from the LED unless I put pressure on the board, and then when I released the pressure, the LED stopped flashing.

    I like the size of this but will have to take it apart and fix it down to a better base or I simply cannot rely on it at all.

    • I don’t see how you could be having a connection jumping rows on you like that (i.e. getting a connection where there shouldn’t be one). It’s basically just four 600 tie-point boards connected together with 5 pwr rails. Do they not have the double sided tape on the back of them? There would have to be something broken for two rows to get cross connected on the inside Man, if that were to happen on a power bus you could fry your chip.

  • Are the binding posts attached to anything?

  • A nice, simple board. Some other breadboards are too tight, others too loose, but this one is just right. Do you think that you guys could possibly supply similar rubber standoffs? I think it needs just a little more support (like one in the middle). I will use something else for the time being.

Exactly what it claims to be

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. :)

Very nice. Needs better feet.

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.

work as intended so far

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?

One Big Breadboard

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.

Just Perfect!

Deffinately worth buying!

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.)

Love it

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.

Great value for the money

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. :-)
