2.54mm 40P Dupont Jumper Wires – 20cm
$2.00
These 2.54mm 40P Dupont jumper wires are designed for breadboards, development boards, sensor modules, PCB debugging, and low-voltage signal connections. Each cable set uses copper core conductors, a 20cm wire length, and color-coded ribbon wiring for easier pin identification. Available in female-to-female and male-to-female versions.
1. Standard 2.54mm Pitch
Compatible with common 2.54mm pin headers, breadboards, sensor modules, microcontroller boards, and PCB test interfaces.
2. 40P Color-Coded Ribbon Cable
Includes 40 jumper wires in a color-coded ribbon format, making signal tracing, channel management, and wiring checks easier.
3. 20cm Practical Length
The 20cm length is suitable for desktop prototyping, board-to-module connections, and short internal wiring inside test setups.
4. Copper Core Conductors
Uses copper core wires for stable conductivity in low-voltage signal connections and daily electronics debugging.
5. Two Connector Options
Available in female-to-female and male-to-female versions to support different board, module, and pin header connection needs.
Overview
These 2.54mm 40P Dupont jumper wires are practical connection cables for electronics prototyping, PCB debugging, sensor module wiring, and development board testing. The 20cm cable length works well for breadboard experiments, desktop development, and short-distance internal wiring.
Each set includes 40 color-coded wires, which can be used as a ribbon cable or separated into individual wires as needed. The copper core conductors are suitable for low-voltage signal wiring, common development testing, and general electronic connection tasks.
Two versions are available: female-to-female for connecting two pin-header interfaces, and male-to-female for connecting pin headers to sockets, breadboards, or development modules.
Variant Options
| SKU | Connector Type | Recommended Use |
|---|---|---|
| 63.700.000017 | Female-to-Female | Board-to-board or module connections where both sides use male pin headers |
| 63.700.000018 | Male-to-Female | Pin header to socket, breadboard, or module interface connections |
