20cm 40 Pin Female to Female Arduino Jumper Wires

The 20cm 40 Pin Female to Female Jumper Wires are reusable 2.54mm Dupont-style connecting wires for Arduino, ESP32, STM32, Raspberry Pi, breadboard projects, sensors, modules and electronics prototyping. The multicolor ribbon contains 40 separable female-to-female wires for quick solderless connections between compatible male header pins.

Description

The 20cm 40 Pin Female to Female Jumper Wires provide a convenient and reusable way to connect development boards, sensors, modules and other electronic components with compatible male header pins.

Each jumper wire has a female socket connector at both ends, making it particularly useful for connecting two devices or modules that expose compatible male headers. Unlike male-to-male or male-to-female jumper wires, this version is designed specifically for female-to-female connections.

The set contains 40 multicolor jumper wires arranged as a flexible ribbon. Individual wires can be separated from the ribbon when required, or several wires can remain together to create an organized wiring harness. Current Pakistan listings also describe these products as 40-wire separable ribbon cables.

Each wire is approximately 20cm (200mm / 8 inches) long, providing useful reach when connecting development boards, sensors, displays and other modules during circuit prototyping.

These Dupont jumper wires are designed for commonly used 2.54mm (0.1-inch) pitch headers. Both female ends fit over compatible 2.54mm male header pins. This 2.54mm compatibility is also documented by multiple current Pakistani electronics listings.

Arduino Jumper Wires

These female to female jumper wires are useful for Arduino projects where compatible male header pins need to be connected to sensors, modules, displays or other electronic hardware.

Arduino is an important application, but these wires are not limited to Arduino.

They can also be used with compatible:

• ESP32 development boards
• ESP8266 boards
• STM32 development boards
• Raspberry Pi GPIO headers
• Sensor modules
• Display modules
• Relay modules
• Motor driver modules
• PCB headers
• Development boards
• Robotics hardware
• IoT projects

Current Pakistani listings likewise describe female-to-female jumper wires for Arduino, Raspberry Pi, development boards, PCB projects and general electronics prototyping.

Female to Female Connector Design

This version has:

End 1 → Female Socket
End 2 → Female Socket

This configuration is useful when both devices expose male header pins.

For example:

Development Board Male Header → Female Jumper Wire → Sensor Module Male Header

Always check the header gender and 2.54mm pitch compatibility of the devices before connecting them.

FAQs

1. What are female to female jumper wires?

Female to female jumper wires have female socket connectors at both ends. They are used to connect development boards, sensors, modules and other electronics that have compatible male header pins.

2. What is the length of these jumper wires?

Each jumper wire is approximately 20cm (200mm) long.

3. How many jumper wires are included?

The ribbon contains 40 multicolor female-to-female jumper wires that can be separated individually or into smaller groups.

4. What is the connector pitch?

These are 2.54mm Dupont-style jumper wires, suitable for commonly used compatible 2.54mm male headers.

5. Can I use these jumper wires with Arduino?

Yes. These Arduino jumper wires can connect compatible Arduino hardware to sensors, displays, modules and other components equipped with suitable male headers.

6. Are these jumper wires only for Arduino?

No. They can also be used with compatible ESP32, ESP8266, STM32, Raspberry Pi GPIO, sensors, modules and general electronics projects.

7. Can female to female jumper wires be used with a breadboard?

Yes, they can be used as part of breadboard projects, particularly for connecting boards, sensors or modules that expose male headers.

However, because both ends are female sockets, these wires are not intended for direct insertion into standard breadboard holes. A male-ended jumper wire is normally required for direct breadboard insertion.

8. What jumper wires are best for direct breadboard connections?

For direct insertion into a standard solderless breadboard, male-to-male or male-to-female jumper wires are generally used depending on the connector at the other end.

Female-to-female wires are better when both components have male header pins.

9. Can I use female to female jumper wires with ESP32?

Yes, provided the ESP32 board and the device being connected expose compatible 2.54mm male headers.

10. Can these wires be used with STM32?

Yes. They are useful in STM32 prototyping for connections between compatible development boards, programmers, modules and other male-header-equipped hardware.

11. Can I use them with Raspberry Pi?

Yes. Female jumper sockets can connect to compatible Raspberry Pi GPIO header pins. The required connector at the other end depends on the device being connected.

12. Can these jumper wires connect sensors and modules?

Yes. This is one of their most useful applications. They can connect compatible sensors, displays, relay modules and other boards that expose 2.54mm male header pins.

13. Do female to female jumper wires require soldering?

Normally no. They provide reusable solderless connections between compatible header pins.

14. Can the 40-wire ribbon be separated?

Yes. Individual wires or smaller groups can be separated according to the number of connections required.

15. Are these Dupont jumper wires reusable?

Yes. They can be disconnected and reused across different electronics projects as long as the connectors remain in good condition.

16. What is the difference between female-to-female and male-to-female jumper wires?

Female-to-female: female sockets on both ends.

Male-to-female: male pin on one end and female socket on the other.

Choose the version according to the connector gender of the boards or modules you need to connect.

17. What is the price of female to female jumper wires in Pakistan?

The female to female jumper wires price in Pakistan may vary with stock and market conditions. Check Chip.pk for the latest product price and availability.
