5V 31mm High-Bright RGB Auto-Color-Fading MCU LED Light Board
TheRTRLED 31mm High-Bright RGB Auto-Color-Fading LED Light Board is an advanced, premium-grade circular LED module engineered for creators, hobbyists, and electronic DIY enthusiasts who demand enhanced luminosity.
Featuring an integrated U1 control IC (Microcontroller Unit) and dedicated transistor drivers (QB, QR, QG), this high-bright board automatically cycles through a smooth, beautiful RGB color-gradient fade effect—no external controllers, drivers, or programming required!
Simply connect to a 5V power source, and watch your creations come to life with seamless, vibrant, and high-intensity color transitions.
Key Features
- Smart Integrated MCU (Auto-Fading): Eliminates the hassle of wiring complex RGB controllers. The dedicated onboard intelligent microcontroller coordinates a seamless, multi-color gradient fading cycle right out of the box.
- High-Bright Pro-Grade Output: Unlike basic modules, this upgraded board utilizes a multi-stage circuit configuration with independent color-channel transistors (QB, QR, QG) to deliver maximum brightness, striking pure color output, and low heat generation.
- Safe & Stable 5V DC Operation: Fully compatible with common 5V power sources. You can easily power it via USB cables, smartphone chargers, power banks, or AA/AAA battery boxes.
- Advanced Circuit Protection & Stability: Features an onboard capacitor (C1) for voltage smoothing and precisely matched inline SMD resistors to protect the components from voltage spikes, ensuring a long operational lifespan.
- DIY-Friendly & Ready to Solder: Designed with large, clearly marked Positive (+)andNegative (-) tinned soldering pads for quick, easy, and secure wire connection. The circular PCB also features integrated screw positioning channels for hassle-free mounting.

Versatile Applications
This 31mm round high-bright LED panel is the perfect universal light engine for a wide array of creative lighting applications:
- 3D Acrylic Night Lights: Perfect premium upgrade light board for wooden or plastic LED lamp bases.
- Resin & Glass Crafts: Deeply illuminate crystal spheres, thick epoxy resin art, and glass ornaments from within.
- Scale Models & Dioramas: Add high-intensity, futuristic glowing effects to architectural models or sci-fi dioramas.
- Custom Gadget Modding: Great for cosmetic PC case lighting, custom desk toys, or decorative accent lights requiring higher visibility.
Installation Note
Please ensure correct polarity during soldering: connect to the Positive (+) and Negative (-) terminals accordingly. Do not connect to power sources exceeding 5V DC to prevent permanent damage to the chip.
