Know before you buy
Yes, these wires are specifically designed for standard solderless breadboards. The 22AWG gauge is the industry standard for ensuring a secure, snug fit in breadboard sockets.
No, the wires come pre-cut, stripped, and pre-bent. They are ready to be plugged directly into your breadboard right out of the box.
The kit includes 14 different lengths ranging from 2mm to 125mm. With 10 pieces of each length, you have plenty of options to keep your circuit layouts clean and organized.
These wires are made with high-quality silicone insulation. This material provides excellent flexibility, making it easy to route wires around components without them snapping or losing their shape.
This kit is intended strictly for prototyping on breadboards. Because they are pre-bent and designed for temporary connections, they are not suitable for permanent soldering or final product assembly.
