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.
