Specifications

• Cable Type: Male to Female (M-F) Dupont Jumper Wire
• Pitch Compatibility: 2.54mm (0.1") Standard Mil Spacing
• Length: 10cm (approx. 4 inches)
• Quantity: 40 Individual Wires (provided as a single 40-pin ribbon)
• Wire Gauge: 24 AWG
• Colors: Chromatic 10-color repeating sequence for easy trace identification
• Material: High-quality copper core with flexible PVC insulation
• Connection Style: Solderless crimped headers

 Applications

• Raspberry Pi Prototyping: Perfect for connecting sensors, relays, and displays directly to the Pi's male GPIO pins.
• Sensor Interfacing: Quickly hook up modules (like ultrasonic sensors or OLEDs) to a breadboard or microcontroller.
• PCB Debugging: Temporarily bridge connections on custom PCBs with standard 2.54mm headers.
• Modular Sub-Assemblies: Tear off a group of 4 or 5 wires to create a clean, unified cable for an I2C or SPI module.

Unlock New Capabilities

• Past Projects: If you've been using solid-core hookup wire or bare wire stripping, you know how fragile and time-consuming wiring can be.
• Feature Upgrade: This 40-pin ribbon unlocks modularity. You can peel off exactly the number of wires you need (e.g., a block of 4 for an I2C OLED) keeping your signal lines organized and preventing accidental cross-wiring.
• Effort Level: Beginner. Simply plug and play.

Package Includes:

• 1 x Male To Female Jumper Wires 40 Pcs 10cm

Frequently Asked Questions (FAQ)

• What is the length of these jumper wires?
  They are exactly 10cm (approx. 4 inches) long, perfect for short, clean connections.
• What is the pin pitch compatibility?
  Both the male and female ends are designed for standard 2.54mm (0.1 inch) pitch headers.
• Can I tear the ribbon into individual wires?
  Yes, the 40-pin ribbon is designed to be easily peeled apart into single wires or smaller multi-wire groups (e.g., groups of 4 for I2C).
• Are these compatible with Raspberry Pi GPIO pins?
  Absolutely. The female end plugs perfectly onto the Raspberry Pi's male GPIO header.
• Will the male ends fit into a standard breadboard?
  Yes, the square male pins are sized to fit snugly into standard breadboard tie-points.
• What is the maximum current rating for these wires?
  These are intended for low-power signal logic. We recommend keeping current well below 1A (ideally <500mA) to prevent voltage drops.
• Can I use these for 5V and 3.3V logic circuits?
  Yes, they are perfectly safe for standard 5V and 3.3V digital and analog signals.
• Are the connectors soldered or crimped?
  The metal terminals inside the black plastic housings are machine-crimped to the wire for durability.
• Can I connect two wires end-to-end to make a 20cm wire?
  Yes, you can plug the male end of one wire into the female end of another, though it's better to buy 20cm wires to avoid signal noise and loose joints.
• What wire gauge (AWG) are these cables?
  They use standard prototyping wire, typically around 24 AWG.
• Do the colors follow standard resistor color codes?
  Yes, the ribbon typically repeats a 10-color chromatic sequence (Brown, Red, Orange, Yellow, Green, Blue, Purple, Gray, White, Black).
