5mm

5 mm LEDs are a standard, easy‑to‑mount light source for a wide range of electronic and robotic projects. Available in single‑colour, RGB and infrared variants, they provide typical forward voltages around 2‑3 V and operate reliably at 20 mA, making them compatible with most microcontroller outputs and driver circuits. Some units include an integrated resistor, simplifying wiring and reducing the risk of accidental overload, while others use common‑anode or common‑cathode pins for flexible colour mixing. Brightness levels vary from standard to high‑intensity types, suitable for indicators, status lights, visual feedback or sensor illumination. Packs are often supplied in reusable ESD‑safe bags, facilitating bulk use and inventory management.
