Adafruit
Hook-up Wire Spool Set - 22AWG Solid Core
Best wire set for electronics hobbyists building breadboard and perfboard projects.
This is a fantastic set for any electronics enthusiast! You get a box containing **ten** spools of **22 AWG solid-core** hook-up wire, with each spool holding **25ft** of wire. The solid core makes it easy to solder and ensures the wire holds its shape nicely when you bend it, which is super handy for breadboards, perfboards, and terminal blocks. The set comes organized in a box with a plastic dowel rod for easy spool rotation and little punch-outs to keep the wire ends tidy. It's a great all-around gauge to have on hand!

What customers say
The Adafruit Hook-up Wire Spool Set (22AWG Solid Core) garners overwhelmingly positive sentiment, establishing itself as a staple for electronics prototyping and breadboarding across the maker community. Customers frequently highlight the exceptional convenience provided by the multi-color spool set, which significantly aids in circuit organization and debugging—a critical feature for complex projects where clear signal path identification is paramount. The quality of the wire itself is consistently praised; the 22AWG solid core is deemed the perfect gauge for insertion into standard breadboards and terminal blocks, maintaining its shape well without being overly stiff or prone to breakage during repeated use. Reviewers appreciate the durable yet flexible PVC insulation, noting that it strips cleanly and easily without nicking the copper strands, which speaks volumes about the manufacturing precision and quality control Adafruit is known for. While the initial price point is sometimes noted as slightly higher than bulk, generic alternatives found elsewhere, the consensus is that the superior quality, reliable gauge consistency, and the sheer utility of the color-coded spools justify the investment. Users often mention that the frustration saved by using high-quality wire that consistently performs outweighs any minor cost difference. This product is viewed less as a simple commodity and more as a reliable, essential tool that enhances the efficiency and success rate of electronic projects, making it a high-value purchase for both novice hobbyists learning the ropes and seasoned engineers requiring dependable components for rapid prototyping.
Know before you buy
Yes, 22 AWG solid-core wire is the industry standard for breadboarding. It is rigid enough to insert easily into the spring clips without bending or fraying.
Solid-core wire is stiffer than stranded wire, which means it holds its shape once bent. While this is excellent for keeping your wiring neat and organized, it is less flexible and can be prone to snapping if bent back and forth repeatedly.
The set includes ten spools, each featuring a different color. This variety is helpful for color-coding your power, ground, and signal lines to keep complex circuits easy to troubleshoot.
22 AWG wire is generally rated for low-to-moderate current, typically up to about 5-7 amps depending on the length and insulation type. It is best suited for signal wiring, logic-level connections, and low-power components rather than high-power motors or heating elements.
The box acts as a dispenser. You can mount the spools on the included dowel rod and pull the wire through the punch-outs on the front, which prevents the spools from tangling or unspooling accidentally while you work.
