Problem & Solution
Electronics prototyping requires quick, reliable connections between microcontrollers, sensors, modules, and solderless breadboards. Custom wire stripping and soldering slow down experimental circuit builds and increase the risk of loose pins or short circuits.
These 20cm Dupont jumper cables offer pre-crimped connector ends in Male-to-Male, Male-to-Female, and Female-to-Female configurations. Supplied as peelable rainbow ribbon cables, they allow makers to peel off single wires or custom multi-pin buses, streamlining circuit assembly on standard 2.54mm pin headers.
Who Is It For?
Designed for electronics hobbyists, STEM students, robotics builders, and engineers working with Arduino, Raspberry Pi, ESP32, and breadboard circuits. Ideal for anyone building sensor arrays, breakout board connections, or micro-controller prototypes.
Key Features
- Triple Connector ConfigurationsProvides Male-to-Male, Male-to-Female, and Female-to-Female options for linking microcontrollers, sensors, and breadboards.
- 20cm Wire LengthOffers comfortable reach between modules while preventing excessive wire clutter in small enclosures.
- Peelable Ribbon CableFlat ribbon structure allows individual or grouped wires to be separated easily for custom cable assemblies.
- Standard 2.54mm Terminal PitchFits standard electronic breadboards, Arduino headers, Raspberry Pi GPIO pins, and sensor breakouts.
- Multi-Color InsulationColor-coded wires make visual circuit tracing fast and straightforward during debugging.

Pros & Cons
Pros
- Covers all standard connection terminal types (M-M, M-F, F-F) required for prototyping
- Practical 20cm length provides flexibility across tabletop breadboards and enclosures
- Ribbon design peels apart cleanly without damaging individual wire insulation
- Fits standard 0.1-inch (2.54mm) pitch pin headers securely
Cons
- 20cm length may be unnecessarily long for tightly compact micro-breadboards
- Designed for low-current signal and logic wiring, not high-current power distribution
- Exact AWG wire gauge and insulation dielectric rating are not specified in available data
FAQ
The set includes Male-to-Male (M-M), Male-to-Female (M-F), and Female-to-Female (F-F) jumper cables depending on the selected package count.
Yes, the flat 40-pin ribbon cable can be peeled into individual strands or custom multi-wire sets like 2-pin, 4-pin (I2C), or 8-pin buses.
They feature standard 2.54mm (0.1 inch) pitch connectors, making them direct fits for standard breadboards, Arduino pins, and Raspberry Pi headers.
No, these are signal-level jumper wires intended for low-voltage microcontroller logic, digital sensors, and prototyping, not for high-power loads.
Final Verdict
A reliable, fundamental accessory set for anyone working with microcontrollers and breadboards. Recommended if you need adaptable Male, Female, and ribbon connection options for standard 2.54mm header pins. Skip if your build requires custom ultra-short lengths or heavy-gauge current carrying.
