Solderless breadboards are one of the most useful things out there. Without them, prototyping circuits becomes a lot more cluttered or a lot more permanent! This breadboards feature rows of interconnected sockets, but does not have the power rails like larger breadboards. Components can be placed in the breadboard and connected up using hookup wire or jumper wire to test a circuit, changed as necessary, and eventually ported to a more permanent solution once all the bugs are worked out.

This mini breadboard has 170 tie points in 34 interconnected rows. The board is 1.4″ x 1.6″ x 0.3″(3.5 cm x 4.5cm x 0.9cm) and is even small enough that it can be mounted on some Arduino Shields between the headers.
