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)

  • 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.

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

  • 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.
