Overview

This is the female-Dupont variant of our 10-piece alligator-to-jumper test-lead set. One end is a colour-coded insulated alligator clip; the other end is a 0.1" (2.54 mm) female Dupont jumper that slides directly onto the male header pins on a development board, sensor module, or daughterboard. Use them to clip onto component leads or probe points and route a clean signal straight onto an Arduino, ESP32, Raspberry Pi GPIO, or any 0.1" pin header without disturbing your wiring.

The female end is what you want when the target board has exposed male pins (most Arduino-compatible boards, sensor breakouts, the Pi GPIO header). For driving a breadboard or accepting a male jumper, choose the male-end variant.

Connection Examples

Connecting to Arduino-Style Headers

The female Dupont end slides directly onto the male pins of an Arduino Uno, Nano, Mega, or any module that exposes a 0.1" male header. Use the alligator end to clip onto a battery, switch, sensor probe, or test lead.

Lead Color Alligator End Female End to Pin
Red Battery + / 5V probe 5V or VIN
Black Battery − GND
Yellow Sensor signal lead Analog input (A0…A5)

Raspberry Pi 40-pin GPIO Header

The Pi's GPIO is exposed as 40 male pins. The female Dupont end slides over a single pin. Use the alligator end to grab a probe, push-button wire, or LED lead.

Voltage Warning: Pi GPIO is 3.3V logic only. Do NOT clip the alligator end onto a 5V signal source unless you've confirmed the Pi pin can handle it — only the Pi's 5V power pins (Pin 2, 4) are 5V-tolerant; the GPIO pins are 3.3V max.

Probing a Live Circuit

Clip onto a TP test point, exposed via, capacitor lead, or component pin to grab the signal, and feed it into an oscilloscope or microcontroller via the female Dupont end.

Tip: Use shorter clips for high-frequency signals — 30 cm of unshielded wire forms a good antenna for nearby switching noise. For digital signals above 1 MHz consider using oscilloscope probes instead of these leads.

Frequently Asked Questions

What's the difference between the male and female versions?
The Dupont end. Female slides over a male pin (e.g., Arduino headers, Pi GPIO). Male plugs into a female socket or breadboard hole. Pick female if you're connecting to dev-board headers; pick male if you're going into a breadboard or female header on a custom PCB.
Can I daisy-chain two of these end-to-end?
Not directly — both ends of these leads are different connector types, so you can't plug two female-end leads together. To extend, use a male-end lead and a female-end lead, or splice with a male-male jumper in the middle.
Can I use these on mains AC?
No — these are rated for ~30V DC and the insulation is hobbyist-grade. Use proper CAT-rated test leads for any mains-voltage work.
The female socket is loose on the male pin.
Over time, Dupont female sockets can lose tension. Use a small flat screwdriver to gently pinch the metal contact inside the female housing — this restores the spring grip. Be careful not to bend it sideways.
Are the wires solid-core or stranded?
Stranded copper, ~22 AWG. Stranded wire flexes much better than solid for clip-and-go applications and won't fatigue and break at the alligator end.
