5V 31mm 3-Color Intelligent MCU LED Light Board Smart Color-Switching Aluminum Panel with Built-In Controller (Red / Blue / Purple)

Elevate your custom lighting and creative projects with this highly advanced, ultra-compact circular multi-color LED light board. Measuring 31mm in diameter, this module features an onboard MCU (Microcontroller Unit) chip that allows you to easily switch between three distinct atmospheric light modes—Vibrant Red, Deep Blue, and Moody Purple—using a standard push-button setup. Built on a heavy-duty aluminum core substrate for superior cooling and powered by a safe 5V DC input, it is the ultimate smart core for custom gaming setups, sci-fi models, and premium DIY art installations.

Key Features

Intelligent 3-Color Ambient Switching: Features an onboard MCU chip that cycles through three distinct colored lighting modes via external push-button control: Vibrant Red, Deep Blue, and Moody Purple (Combined). Enjoy complete color customization from a single board!
Ultra-Compact 31mm Smart Profile: Combines a high-density color LED layout and an integrated smart control chip on a tight circular profile with a central hole, making it ideal for space-saving custom fixtures, mini accent lamps, and intricate 3D prints.
Premium Aluminum PCB Substrate (MCPCB): Engineered with a high-thermal-conductivity aluminum core that rapidly draws heat away from both the LEDs and the MCU chip, ensuring long-term reliability and prevention of light degradation.
High-Impact Multi-Color SMD LEDs: Populated with high-efficiency LED chips designed to output rich, deeply saturated colors that deliver a striking cyberpunk, sci-fi, or aesthetic neon vibe.
Safe & Universal 5V Low Voltage: Runs smoothly on standard 5V DC power. Perfect for integration with standard USB cables, mobile phone chargers, portable power banks, or 5V battery packs.
Durable, Ready-to-Solder Interface: Features clearly labeled, pre-tinned pads for seamless integration with your choice of input power (+) and (-), along with dedicated connections for your toggle/push button.

Ideal Applications

Gaming & Desktop Accents: Great for specialized under-desk mood lighting, custom PC chassis modding, or adding a bold multi-color accent light source to acrylic displays, trophies, and bedroom nightlights.
Creative DIY & 3D Printing: An ideal light source for anime/mech-themed figures, sci-fi scale models, cosplay props (such as glowing futuristic armor cores or magic circles), and vibrant resin crafts.
Themed Holiday & Event Decor: Perfect for adding an energetic ambient touch to party settings, live-streaming backdrops, unique retail showcases, and theatrical lighting effects.
