20cm Male to Female Jumper Wires (40 PCS) for Arduino, ESP32 & Breadboards

20cm Male to Female Jumper Wires – 40 PCS (Dupont Breadboard Cables)

These 20cm Male-to-Female Dupont Jumper Wires bridge the gap between breadboard rows and module pin headers, making them indispensable for mixed prototyping setups. The 40-piece color-coded set ensures clean, traceable wiring in any project.

Key Specifications

• Length: 20cm (200mm)
• Connector Type: Male to Female (M-F) Dupont
• Quantity: 40 pieces
• Pitch: 2.54mm (0.1") standard
• Wire Gauge: 26 AWG flexible stranded copper
• Insulation: PVC / flexible jacket

Compatibility & Use Cases

M-F jumper wires are the most versatile type, connecting breadboard tie points to female-header modules and vice versa. Compatible with Arduino, ESP32, Raspberry Pi, NodeMCU, and all 2.54mm pitch boards. Common applications include:

• Connecting Arduino/ESP32 GPIO pins to breadboard circuits
• Wiring sensor modules (DHT11, HC-SR04, PIR) to dev boards
• Linking relay and motor driver modules to microcontrollers
• IoT prototype assembly without soldering
• STEM and educational electronics kits

The flexible stranded copper core ensures reliable contact even after repeated bending and reconnection.
