![]() Each of the rows of 5 holes has internal spring contacts that connect the 5 holes electrically. ![]() These holes are sized to allow wire of up to 20 AWG to be inserted. The breadboard consists of a plastic housing usually made of ABS plastic that has a series of holes arranged in rows of 5. When we use the term ‘breadboard’ here we are referring only to solderless breadboards.ġ1.7 Wiring Up The Power Breadboard Basicsįor anyone new to breadboards, they are simple yet clever devices so a quick introduction is probably in order. The term breadboard is also sometimes use for prototype PCBs or perf boards which are designed to prototype a circuit by soldering the components in place and making connections using wires. For that reason and for the foreseeable future many of the new and more interesting SMT devices will continue to be adapted for use with solderless breadboards by mounting them on breakout boards of some type so that hobbyists don’t need to design and fabricate a PCB every time they want to work with a circuit.įor the sake of brevity, we will refer to solderless breadboards as just breadboards for the rest of this article. While SMT components are better in almost every other way compared to leaded parts, there is no easy way to directly prototype with these newer SMT devices without designing a PCB to mount them. In many ways they seem old school in today’s world where most components are going Surface Mount Technology (SMT). Solderless breadboards have been around for a long time and are designed to be used with components that have leads such as DIP style ICs and leaded resistors and capacitors. Since good information on solderless breadboards can be hard to come by, we have created this guide to help. That leads to wondering what you are getting for your extra money if you pony up for the more expensive version or if you would be OK if you just get the cheaper one. If you are shopping for a solderless breadboard here on our site or elsewhere, you may be wondering why two basically identical looking solderless breadboards have significantly different prices. ![]() This solderless breadboard guide provides information on how they are constructed and used and how to select the best one for your requirements.
