Frequently asked questions
What is the tinned tail for?
The tinned tail, about 3 mm, keeps the copper end clean and easy to insert into breadboard holes or header pins without fraying.
Why use different colors for jumper wires?
Colors help organize a circuit, for example using black for ground and other colors for signal or power lines, which makes wiring easier to read and debug.
