RGB-Matrix-P4-64x32

Overview

This product is a bare screen requiring a main control board such as Raspberry Pi, ESP32, or Arduino for display. Please refer to the list for details.

Introduction

The RGB-Matrix-P4-64x32 is a 64 x 32 RGB LED matrix panel featuring 2048 individual RGB LEDs with a 4mm pitch. It supports controllers like Raspberry Pi and Arduino, providing open-source demos and tutorials. This makes it suitable for makers and electronics enthusiasts for learning, DIY secondary development, or creating desktop or wall-mounted display applications.

Features

• 2048 individual RGB LEDs for full-color display with adjustable brightness.
• 64 x 32 pixels with a 4mm pitch, enabling the display of text, colorful images, or animations.
• Dimensions: 256mm x 128mm, suitable for DIY desktop or wall-mounted displays.
• Onboard two HUB75 headers: one for controller data input, one for output, supporting chain functionality.
• Provides open-source development resources and tutorials for use with Raspberry Pi, Arduino, and similar platforms.

Specifications

Note: The power supply ports (VCC and GND) require a 5V supply. Do not connect to other voltage levels to prevent damage to the display screen.
