Description

Three 32x8 LED matrix displays, one each in red, green and blue, with colour-matched 3D-printed cases. Wide enough for scrolling messages, clocks and scoreboards.

Highlights

• One colour each. Red, green and blue modules, 256 LEDs apiece; each module is a single fixed colour, not RGB.
• Three signal wires. DIN, CLK and CS drive the whole display, plus power.
• Cascadable. Chain DOUT to DIN to build 64x8, 96x8 or wider.
• Adjustable brightness. 16 levels set in code, with a low-power shutdown mode.
• Cases included. Each module ships with a colour-matched 3D-printed PLA case.
