20cm MaletoMale (M-M) Jumper Wires
Flexible Dupont Cables for Breadboard and Prototyping
These 20cm maletomale jumper wires are essential for electronics projects, providing reliable, solderless connections between components on a breadboard, or from a breadboard to modules with 0.1" (2.54mm) header pins [citation:1][citation:2].
Solderless Connections Male pins on both ends for plugand-play connectivity between breadboards and headers
ColorCoded Ribbon Standard rainbow colors for easy circuit organization and troubleshooting
Wire length is 200mm (20cm) with standard 2.54mm (0.1") pitch connectors.
Wire gauge is typically 28 AWG to 24 AWG copper core with PVC insulation [citation:1][citation:9].
The ribbon can be easily separated into individual wires or kept bundled for neat, organized harnesses [citation:1][citation:5].
Avoid pulling on the wires instead of the connector housing to prevent damage.

Troubleshooting
Loose connection:
- Ensure connector is fully seated on the header pin
- Check for bent pins on the male header or female socket
- Verify the connector size matches the 2.54mm pitch
Wires separating or breaking:
- Pull from the connector housing, not the wire itself
- Limit excessive bending at the connector joint
- Use appropriate strain relief in the finished project
