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.

Like nearly all large breadboards, 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 wont appear at the bottom. Since this often trips people up, Adafruit 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.

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'
