I designed this tiny RGB button LED PCB to make adding colorful, addressable lighting to projects simple and space-efficient. These boards are extremely small yet powerful, making them ideal for applications where size, brightness, and ease of wiring matter.

Each PCB features a NeoPixel-style RGB LED with a built-in constant-current driver, so brightness remains stable even when the supply voltage fluctuates. The LEDs are fully addressable and chainable, allowing multiple LEDs to be controlled using just a single data pin. Despite their compact size, these LEDs deliver vivid 24-bit color output with PWM handled internally by the driver IC. Because the current is regulated inside the LED, you get consistent colors and effects while using less external circuitry.

The PCB includes dual sets of solder pads on the back, making wiring easy and flexible. This design works perfectly for RGB buttons, indicators, control panels, UI feedback, decorative lighting, and compact IoT or wearable projects.
