3mm LED Pack (50 PCS)

A 3mm LED Assortment Pack (50pcs) provides a convenient collection of common indicator LEDs for electronics prototyping, circuit testing, and visual feedback applications. The kit includes five frequently used colors—red, green, yellow, blue, and white—making the component set suitable for signal indicators, decorative lighting, and breadboard experiments. Each compact 3mm through‑hole LED is designed for easy integration with microcontroller platforms such as Arduino and other development boards. The mixed‑color LED bundle simplifies rapid experimentation while ensuring reliable visibility and consistent electrical characteristics across typical low‑voltage projects.

Five Essential Indicator Colors

This LED assortment includes 50 pieces divided evenly among five popular colors: red, green, yellow, blue, and white. Such color variety supports status indication, signal differentiation, and creative lighting effects within electronic circuits. Distinct color outputs make the small through‑hole LEDs useful for debugging, teaching demonstrations, and visual alerts in embedded systems, robotics projects, and prototype control panels.

Breadboard-Friendly 3mm Through‑Hole Design

The compact 3mm form factor fits easily into breadboards, perfboards, and custom PCB designs. Clearly defined anode and cathode leads simplify orientation during circuit assembly, reducing wiring errors during prototyping. Longer positive leads and shorter negative leads allow quick visual identification, while the internal plate structure and flat LED body edge provide additional polarity guidance for reliable installation.

Practical Component Kit for Experimentation

This multi‑color LED component set supports electronics experimentation, DIY circuit development, and educational demonstrations. The mixed pack supplies enough units for repeated testing without depleting inventory during iterative prototyping. Hobby electronics builders, embedded system developers, and STEM learning environments benefit from a ready supply of basic indicator LEDs suitable for signal outputs, visual notifications, and decorative circuit lighting.

Common usage scenarios include breadboard prototyping, educational electronics labs, microcontroller status indicators, decorative lighting experiments, and quick visual feedback in embedded development projects.
