A modern solderless breadboard consists of a perforated block of plastic with numerous tin plated phosphor bronze or nickel silver alloy spring clips under the perforations. The clips are often called tie points or contact points. The number of tie points is often given in the specification of the breadboard.
The spacing between the clips (lead pitch) is typically 0.1" (2.54 mm). Integrated circuits (ICs) in dual in-line packages (DIPs) can be inserted to straddle the centerline of the block. Interconnecting wires and the leads of discrete components (such as capacitors, resistors, and inductors) can be inserted into the remaining free holes to complete the circuit. Where ICs are not used, discrete components and connecting wires may use any of the holes. Typically the spring clips are rated for 1 ampere at 5 volts and 0.333 amperes at 15 volts (5 watts).
These breadboards make it easy to try out things hooked up to a arduino mainboard by using wire jumpers. There are 2x 60 rows of interconnected pins (5 per row) and two long rows on both sides – 700 pins in total.Its dimension is 17.6cm x 4.6cm × 8.3cm. Plesae note that it has no self-adhesive backing and no interlocking part.
