A 32×32 full-colour RGB LED matrix panel with 1024 LEDs at 6mm pitch. The larger pitch provides good visibility at greater distances, making it suitable for signage and larger-scale displays. Pre-balanced white output and a 1:16 scan rate with 12 × 16-bit latches handle the display multiplexing.
Requires 13 digital pins (6 data + 7 control) and continuous redrawing for PWM colour. On a 16 MHz Arduino, 12-bit colour (4096 colours) is achievable at ~40% CPU usage. Higher-performance controllers (FPGA, Raspberry Pi, Propeller) can drive these panels to their full potential. Panels are chainable via IDC connectors.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- RAM
- RAM is temporary memory used while a device is running, and its contents are lost when power is removed. A “Run in RAM” mode is useful for testing settings without permanently programming the module, but it may not support every feature.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
