20cm FemaletoFemale (F-F) Jumper Wires
= Flexible Dupont Cables for Prototyping and PCB Connections =
These 20cm femaletofemale jumper wires are essential for electronics projects, providing reliable connections between standard 0.1" (2.54mm) pin headers without soldering . The cables are constructed from flexible ribbon wire with pre-crimped female sockets on both ends, compatible with square post headers, Arduino boards, and breadboards .
Solderless Connections Preterminated female sockets provide plugandplay connectivity between male headers on boards and modules.
ColorCoded Ribbon Standard 10-color rainbow ribbon simplifies circuit organization and troubleshooting .
Wire length is 200mm (20cm) with standard 2.54mm (0.1") pitch connectors .
Wire gauge is typically 26 AWG or 30 AWG copper core with PVC insulation .
Ribbon cables can be easily separated into individual wires or kept bundled for neat harnesses .
Use female connectors to connect to male header pins on Arduino, sensors, or modules. Avoid excessive force during insertion.

= Troubleshooting =
Loose connection:
- Ensure connector is fully seated on the header pin.
- Check for bent or damaged pins on the male header.
- Verify the connector size matches the 2.54mm pitch.
Wires separating or breaking:
- Avoid pulling on the wires instead of the connector housing.
- Limit excessive bending at the connector joint.
- Use appropriate strain relief in the finished project.
