LED Assortment Kit 200 Pieces 3mm and 5mm A versatile set of 200 throughhole LEDs in two common sizes for prototyping, repairs, and DIY lighting. Includes an assorted mix of red, green, blue, yellow, and white LEDs suitable for breadboards, hobby electronics, indicator lights, and small projects. Key benefits Ready to use assortment saves time: wide selection of colors and two sizes covers most basic electronics needs without separate orders. Easy prototyping and repairs: standard 3mm and 5mm leaded LEDs plug directly into breadboards and PCBs for rapid testing and replacements. Low power and low heat operation: LEDs provide visible light with minimal energy consumption, suitable for battery powered projects and continuous indicators. Durable and simple to install: epoxy lens with metal leads for reliable mechanical and electrical connection. What makes this kit stand out Comprehensive mix: 200 pieces in a single box with both 3mm and 5mm diameters and five common colors, reducing the need to source individual components. Universal compatibility: fits standard breadboards, perfboards, and through hole PCBs. Works with typical LED drivers, resistors, and microcontroller output pins. Practical for beginners and experienced makers: useful for education, prototypes, and finished hobby builds. Key attributes Quantity: 200 pieces per box Sizes: 3mm and 5mm diameter leaded LEDs Colors: red, green, blue, yellow, white Material: epoxy lens with metal leads and semiconductor die Function: indicator light, signal, illumination in lowpower circuits Compatibility: compatible with standard breadboards, perfboards, through hole PCBs and common LED driving circuits Notes on use: observe polarity when installing; use an appropriate currentlimiting resistor or driver to match your circuit Typical applications Electronics prototyping and testing: quickly populate breadboard circuits for visual feedback during development. Hobby projects and model lighting: add running lights, indicators, and accents to scale models, RC builds, and decorative projects. Education and training: teach basic circuits, soldering, and microcontroller output using a durable, varied set of LEDs. Included in the box 200 assorted 3mm and 5mm LEDs in red, green, blue, yellow, and white ready for immediate use. Practical tips Identify polarity: longer lead is typically the anode. For molded 5mm LEDs, the flat side of the rim usually marks the cathode. Protect LEDs with a resistor or current driver sized for your supply voltage and target brightness. For soldering, minimize heat exposure time to avoid damaging the semiconductor. This kit provides a practical, readytouse selection of common LEDs for makers, students, and work, offering flexibility across a wide range of lowvoltage lighting and indicator tasks.
