400 hole solderless breadboard, 8.5cm x 5.5cm. A great solution for prototyping electronics. No soldering required means it can be reused many times for many different projects, allowing for experimenting with circuit design. Many electronics systems can be prototyped using breadboards, from small analog or digital circuits through to complete CPUs.

Has a standard double-strip in the middle and two power rails on both sides which can be pulled off easily to make the breadboard as thin as 3.5cm and stick it onto an Arduino protoshield. The breadboard also be cut in half with a saw to create 2 tiny breadboards, or "snap" these breadboards together either way to make longer and/or wider breadboards.

Standard 2.54mm spacings. All ICs, transistors, diodes, leds and passives can be used on this breadboard. Uses solid hook up wire for interconnections. Boards are keyed to enable easy expansion.
9.7mm thick, including sticky foam on the bottom.
