Large Solderless Breadboard
Product Images and Video
For really big projects, give yourself some room to work in, with a massive 2250-point breadboard - equivalent in size to three full-sized breadboards side by side.
The breadboards are mounted onto a metal plate and comes with 4 colored posts you can use with a bench-top supply. Four bumpers are included, to keep the board from slipping around your desk.
As of April 20, 2018, this breadboard has contiguous power rails. We used to sell a version where the 'power rails' are split in the middle! That means that if you want to plug in a voltage at the top of the board, it won't appear at the bottom. Since this often trips people up, we strongly suggest drawing lines onto the breadboard the moment you get it! Just follow this image to see where the splits occur. Each drawn red line is a split. You can look at the red and blue lines next to the power rails to see if they have a split in them.
Please note, the binding posts for these breadboards are a little smaller than the D-cuts in the metal place, so while they can be screwed into place they 'rotate'
Note: As of Thursday, October 22nd 2015, we are selling the updated version of this product. Drill holes are now 7.9mm in diameter and spaced 17mm apart.
