This is a cute half size breadboard, good for small projects. It's 2.2" x 3.4" (5.5 cm x 8.5 cm) with a standard double-strip in the middle and two power rails on both sides. You can pull the power rails off easily to make the breadboard as thin as 1.4" (3.5cm) and stick it onto an Arduino protoshield. You can also cut these in half with a saw to create 2 tiny breadboards, or "snap" these breadboards together either...

This is a 'full-size' breadboard, 830 tie points. Good for small and medium projects. It's 2.2" x 7" (5.5 cm x 17 cm) with a standard double-strip in the middle and two power rails on both sides. You can pull the power rails off easily to make the breadboard as thin as 1.4" (3.5cm). You can also "snap" these breadboards together either way to make longer and/or wider breadboards. The back is made of foam...

This a tiny little breadboard...half the size of a half-size breadboard! Measures 1.8" x 1.4" (46mm x 36mm ) Perfect for tiny projects and for sticking onto the top of Arduino protoshields!

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...

This cute 3.2″ × 2.1″ (82 × 53mm) solderless half-size breadboard has four bus lines and 30 rows of pins, our favorite size of solderless breadboard for projects. You get a whoppin' 400 tie points ! Plug in a Feather or Metro Mini with the rest for sensors or buttons or even a little display. You can pull the power rails off easily to make the breadboard as thin as 1.4" (3.5cm). You can also cut these in...

Add a micro-slice standard solderless breadboard to your Perma-Proto or other perf-board. This 2x4 point solder-less breadboard is a good way to add some solderless prototyping space if you just need to have a couple points. In our example photo, we put a chip and some jumper wires in the breadboard, but you can use anything with 0.1" spaced header. Comes with one 18mm x 8mm x 8mm piece of solder-less breadboard.  There are...

This is a cute half-size breadboard with an assortment of small jumper wires, great for prototyping. Breadboard is 2.2" x 3.4" (5.5 cm x 8.5 cm) with a standard double-strip in the middle and two power rails on both sides. Power rails can be pulled off easily to make the breadboard as thin as 1.4" (3.5cm). The jumper wires are pre-cut and bent in right angles at the ends, so you can choose the appropriate length for your...

Add a micro-slice standard solderless breadboard to your Perma-Proto or other perf-board. This 4x4 point solder-less breadboard is a good way to add some solderless prototyping space if you just need to have a couple points. Comes with one 18mm x 13mm x 10mm piece of solder-less breadboard.  There are four white posts on the bottom for PCB positioning, but you can cut them off with diagonal cutters if you dont want them.

Add a micro-slice standard solderless breadboard to your Perma-Proto or other perf-board. This 2x8 point solder-less breadboard is a good way to add some solderless prototyping space if you just need to have a couple points. In our example photo, we put a Trinket in the breadboard, but you can use anything with 0.1" spaced header. Comes with one 29mm x 8mm x 8mm piece of solder-less breadboard.  There are two white posts on...
