This project is a custom 15 × 15 RGB LED panel designed as the display core of a pixel-art mood lamp. Its 170 × 170 mm PCB contains 225 individually addressable Worldsemi WS2812B-2427-V6 LEDs at 10 mm spacing.

A serpentine data chain allows an external microcontroller to control the entire panel through one signal output. The board uses a three-wire DATA, GND and regulated 5 V interface, with supply capacitors, an input pulldown and an output test pad for troubleshooting.

Intended applications include pixel art, animated patterns, ambient lighting and a clock. The wider enclosure design includes opaque pixel dividers and a diffuser to form distinct illuminated cells.

To reduce initial prototyping costs, the panel can use an off-the-shelf ESP32 development board with a separate regulated power supply instead of the custom controller PCB.

The LED-board order is currently under PCBWay review. Assembly, firmware integration, pixel mapping, brightness and thermal testing are the next stages. The CAD renders show the intended product, not a completed working prototype.
