Female to Female Jumper Wires 20cm – 10 Pin Dupont Ribbon Cable (Pack of 10 Wires)

20cm Female to Female Jumper Wires (10-Pin Ribbon)

The absolute necessity for any rapid prototyping setup. This is a complete 10-pin ribbon cable of Female to Female (F-F) Dupont jumper wires, measuring 20cm (approx. 8 inches) in length. Because they feature a female socket on both ends, they are specifically designed to connect male header pins together such as connecting your ESP32 Development Board directly to an MPU6050 sensor or an L298N motor driver without the need for a breadboard.

Why choose these jumper wires?

• Tear-Away Ribbon Design: Need 4 wires for an I2C sensor? Simply peel a group of 4 wires off the main ribbon. This keeps your wiring neat, organized, and color-coded.
• Standardized Fit: The 2.54mm (0.1″) pitch connectors slide perfectly onto standard square male header pins, providing a snug, friction-fit connection that won’t easily vibrate loose.
• Breadboard-Free Prototyping: F-F wires allow you to bypass the breadboard entirely, resulting in smaller, more reliable permanent connections inside your robot chassis.

Common Applications

• Connecting modules to a Raspberry Pi (which has male GPIO pins)
• Wiring sensors directly to an ESP32 or ESP8266 board
• Extending the reach of standard 3-pin servo motor cables
• I2C and SPI bus communication lines

Common Questions

Will these work with my Arduino Uno?

The Arduino Uno primarily has Female sockets on its main rails, meaning you would need Male-to-Female or Male-to-Male wires for the Uno. These Female-to-Female wires are best for the ESP32, Raspberry Pi, or connecting two sensor modules directly.

Can I use these for power lines or motors?

These are low-current data wires (typically handling max 1A). They are perfect for logic signals, 5V sensor power, and I2C lines. Do not use these to supply main power to high-draw DC motors, heated beds, or large servo arrays, as the thin wire will overheat.

Why do they feel loose on some components?

Dupont connectors are designed for standard square header pins (0.64mm thick). If you attempt to plug them into round “machine-tooled” pins or extremely thin resistor legs, the connection will feel loose. Always pair them with standard square male headers.

How do I peel them without tearing the insulation?

Instead of pulling the wires apart from the very end (which can stress the black plastic housing), pinch the wires slightly below the hard plastic connectors and peel them apart down the middle of the ribbon. This ensures the housing stays completely intact.
