K-4000C Offline LED Pixel Controller SPI DMX512 Decoder SD Card Programmable Support WS2812 SK6812 5V/12V/24V for LED Strip Light Advertising Signs

No.K-4000C
The K-4000C is a versatile offline LED pixel controller designed for dynamic lighting projects. It supports a wide range of IC chips including WS2812, SK6812, and TM1812, as well as standard DMX512 protocols. By simply storing effect files on an SD card, users can achieve complex animations without needing a computer connection.

With 4 output ports, it can drive up to 4096 pixels simultaneously, making it ideal for large-scale installations. The controller features a wide voltage input (DC5V-24V) for compatibility with various LED strips and fixtures. Its robust design ensures stable performance in commercial advertising, architectural decoration, and stage lighting. Easy to program via LED Edit software, the K-4000C offers both flexibility and reliability for professionals seeking high-quality visual effects.



  • Universal Compatibility:​ Supports various SPI chips (WS2811, WS2812, SK6812, etc.) and standard DMX512 output, suitable for most pixel LEDs.

  • Offline Operation:​ Plays effects directly from an SD card (FAT32 format), eliminating the need for a PC to run continuously.

  • High Capacity:​ Features 4 output ports, controlling up to 1024 pixels per port (total 4096 pixels) for large-scale displays.

  • Wide Voltage Range:​ Operates on DC5V, 12V, or 24V, adapting to different power supply environments easily.

  • User-Friendly Software:​ Compatible with LedEdit-K for easy effect design, file export, and DMX address writing.
