The BMT RGB LED 4P 5MM Common Cathode (10 Pack) is a high-quality, versatile 4-pin RGB LED set designed for electronics projects, prototyping, education, and embedded system applications. Each LED integrates Red, Green, and Blue light sources in a single 5mm package, allowing full-color mixing to produce millions of colors using PWM (Pulse Width Modulation) control.
These LEDs use a common cathode configuration, meaning all three LED colors share a single negative (-) pin, while the Red, Green, and Blue channels are independently controlled via separate positive pins. This makes them ideal for use with Arduino, Raspberry Pi, microcontrollers, PLCs, development boards, and logic controllers.
The water-clear/diffused lens provides excellent brightness, smooth color blending, and wide-angle visibility. With a 120 luminous angle, these LEDs deliver consistent light distribution, making them perfect for indicators, displays, visual effects, and interactive electronics.
Operating at low voltage (1.8V - 3.4V) with a typical 20mA per color channel, these RGB LEDs are energy efficient, safe for low-power systems, and easy to integrate into standard 5V and 3.3V logic environments using current-limiting resistors.
Supplied as a 10-piece pack, this product is ideal for bulk prototyping, classroom kits, production testing, and hobbyist projects.
