Red, Green, Blue with Custom 3D-Printed Enclosures. Each module features a 32x8 dot matrix display (256 LEDs) driven by the MAX7219 IC, packaged in color-matched 3D-printed protective enclosures.
Three LED ColorsRed — high-contrast display, suitable for scoreboards and status displays
Blue — cool tone, suitable for clocks, timers, and notification displays
Green — easy to read, suitable for environmental monitoring and signage
Each module is a single fixed color (not full-color RGB).
Custom 3D-Printed EnclosuresEach module comes with a color-matched, precision-fit 3D-printed case that protects the LED matrix from dust and scratches with a finished look. Suitable for desktop, wall-mount, or project enclosure use.
Cascadable DesignEach module has labeled DOUT and DIN ports for daisy-chaining. Connect multiple modules to build wider displays such as 64x8, 96x8, or larger — suitable for scrolling text, large pixel animations, or multi-color message displays.
