Product Details :

The 50cm Long Alligator Clip Electrical DIY Test Lead Set (5 Pieces) is an indispensable quick-connect wiring solution for electronics laboratories, STEM classrooms, hobbyists, and maker projects. Specially suited for the edge connector pads of the BBC micro:bit, these double-ended crocodile clips allow students and developers to clip directly onto micro:bit pin holes (GND, 3V, Pin 0, Pin 1, Pin 2) without requiring soldering or pin headers.

Each lead is constructed with a flexible 22 AWG multi-strand copper wire core wrapped in durable, flexible PVC insulation. Both ends are fitted with nickel-plated steel alligator clips protected by soft vinyl color-coded insulating boots. The strong spring action of the jaws ensures low-resistance, vibration-resistant electrical contact across component leads, battery terminals, circuit boards, and multimeter probes.

Key Features and Benefits

Ideal for BBC micro:bit & STEM Kits: Large clip jaws grab onto micro:bit edge rings, banana plugs, battery pack leads, and copper foil tapes effortlessly.
5 Distinct Color-Coded Wires: Includes Red, Black, Yellow, Green, and White leads to help keep circuit connections organized and prevent accidental short circuits.
Generous $50 ext{ cm}$ Length: Extended reach enables flexible desktop layout when testing components across breadboards and power supplies.
Strong Spring Action Jaws: Nickel-plated steel jaws open up to $10 ext{mm}$ and grip tightly onto component terminals for hands-free circuit testing.
Protective Insulating Boots: Flexible vinyl boots fully cover the metal clips to protect against accidental shorting when leads touch each other.
