A 32×32 full-colour RGB LED matrix panel with 1024 LEDs at 5mm pitch. Designed for indoor use with a wide 160° viewing angle and pre-balanced white output, these panels look great in ambient light. The slightly larger pitch than 4mm panels makes them well-suited for displays viewed at moderate distances.
The panel uses a 1:16 scan rate with 12 × 16-bit latches. It requires 13 digital pins (6 data + 7 control) and continuous redrawing to achieve 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.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- 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 (random-access memory) is fast, temporary memory a device uses for working data while it is running; in its common volatile form, its contents are lost when power is removed. Some devices offer a mode that applies settings to RAM only, which is handy for testing changes temporarily because they are not stored permanently and disappear at power-off.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
