32x32 RGB LED Matrix Panel - 4mm Pitch

Bring a little bit of Times Square into your home with this totally adorable 5 inch square 32 x 32 RGB LED matrix panel. These panels are normally used to make video walls, here in New York we see them on the sides of busses and bus stops, to display animations or short video clips. They feature 1024 bright RGB LEDs arranged in a 32x32 grid on the front with 4mm grid spacing.

On the back there is a PCB with two sets of dual IDC connectors (two input, two output) allowing chaining multiple panels together. It uses 12 16-bit latches that allow you to drive the display with a 1:16 scan rate.

Comes with:

• Single 32x32 RGB panel
• One 2x8 IDC cable
• Power cable

RAM & Processor Requirements

These displays must be redrawn repeatedly to manually PWM the whole display. They require about 1600 bytes of RAM to buffer the 12-bit color image. Not compatible with Arduino UNO or ATmega32u4 (insufficient RAM). Recommended for high speed, high RAM microcontrollers like SAMD21, SAMD51, ESP32, etc.

Power Requirements

The panel requires up to 4A at 5V when all LEDs are on. Use a regulated 5V 4A power supply for best results.

Connection Requirements

Requires 13 GPIO pins to control. Plug-and-play boards or adapters are recommended for easy wiring. Recommended compatible products include the Matrix Portal ESP32-S3, Matrix Portal with SAMD51, RGB Matrix Shield for Arduino, RGB Matrix FeatherWings, and the RGB Matrix Bonnet for Raspberry Pi.

Note: These panels are remainder stock from factories and may vary visually from batch to batch but maintain the same operation and codebase.
