Overview
This 120-piece set of 10cm multicolored jumper wires is the short-run companion to the classic 20cm Dupont bundle — ideal for tight breadboard builds, compact enclosures, and clean signal routing between neighboring modules. The shorter length keeps your projects tidy, reduces signal noise, and fits where full-length wires just tangle.
The pack includes three connector styles — male-to-male, male-to-female, and female-to-female — so you can bridge breadboards, dev boards, and sensor modules in every direction without swapping cables. All 120 wires use the standard 2.54mm (0.1") Dupont connector that plugs into every Arduino, Raspberry Pi, ESP32, Pico, and sensor breakout on the market.

How to Use
Pick the wire type that matches the endpoints you're connecting: male-to-male for breadboard-to-breadboard jumps, male-to-female for connecting a breadboard to a sensor breakout's female header, and female-to-female for linking two male header boards (like a Pi GPIO to an Arduino).
Separate individual wires by pulling the ribbon apart at the connector end — they're lightly fused together for storage. The wires are narrow enough to fit side-by-side in adjacent breadboard rows without crowding.
Color tip: Stick to a color convention for the lifespan of the project — red for VCC, black (or blue) for GND, and a distinct color per signal. It makes debugging and photographs dramatically easier.
When to choose 10cm over 20cm: Pick 10cm wires when modules sit on the same breadboard or within a palm's width of each other. Longer 20cm wires shine for cross-bench runs or when connecting to boards in a separate enclosure.
Current limit: These wires are rated for signal-level current (1A). For motor power, LED strips, or any load pulling more than 500mA, use dedicated power wires with proper gauge copper instead.
Frequently Asked Questions
What does M-M, M-F, and F-F mean?
M-M is male-to-male (both ends are pin connectors — plugs into breadboards and female headers). M-F is male-to-female (one pin, one socket — great for breadboard-to-breakout). F-F is female-to-female (both ends are sockets — bridges two male-pin boards like a Raspberry Pi GPIO to an ESP32).
How many of each type are in the pack?
The typical split is 40 of each type — 40 M-M, 40 M-F, 40 F-F — giving you 120 wires total. Four of each color within each type.
Will these work with an Arduino, Raspberry Pi, ESP32, or Pico?
Yes, all of them. The 2.54mm Dupont connector is the de-facto standard across Arduino, Raspberry Pi (every model), ESP32, Pico, STM32 Blue Pill, and virtually every hobby sensor breakout.
How much current can one wire safely carry?
1A continuous per wire. Fine for powering sensors, logic signals, and small LEDs. For motors, LED strips, or high-current loads, use properly gauged power wires and dedicated connectors.
Can I split the ribbon into individual wires?
Yes. Gently pull two adjacent wires apart at one end — they'll separate cleanly. You can also keep them as a 4-wire or 8-wire ribbon for clean parallel runs (I2C, SPI, UART bundles).
Should I pick 10cm or 20cm jumper wires?
Use 10cm when your modules are close together (same breadboard, same enclosure). Use 20cm when you need to cross a larger distance or route around obstacles. Many makers keep both lengths on the bench.
