Frequently Asked Questions
Q: What pin pitch do these Dupont jumper wires use?
A: These jumper wires use the standard 2.54mm (0.1 inch) pitch, making them fully compatible with Arduino boards, Raspberry Pi GPIO headers, breadboards, and most development modules and breakout boards available on the market.
Q: Can I use these jumper wires with a Raspberry Pi?
A: Yes! The Female-to-Female and Male-to-Female configurations are perfect for connecting to Raspberry Pi GPIO pins. All three wire types work with any 2.54mm header-based single-board computer or microcontroller.
Q: Are the wires color-coded for easy identification?
A: Absolutely. Each set of 40 jumper wires comes in multiple colors, making it easy to trace connections, organize your circuits, and avoid wiring mistakes during your DIY electronics projects.
Q: Which length should I choose for breadboard prototyping?
A: The 10cm wires are ideal for compact breadboard builds, the 20cm wires offer a good balance of reach and tidiness, and the 30cm wires are best for connecting components across larger setups or between separate boards. Many makers keep all three lengths on hand.
