52Pi RGB LED Matrix Expansion Board for Arduino Nano ESP32, 104 Individually Addressable RGB LEDs Matrix Shield for Arduino

[Description]

The RGB LED Matrix Shield for Arduino NANO R4/ESP32 is a custom-designed expansion board tailored specifically for the Arduino Nano ESP32 or Arduino NANO R4 development platform. It integrates a high-density matrix of RGB LEDs, enabling developers, makers, and hobbyists to create stunning visual effects, dynamic light animations, and interactive displays with minimal wiring.

This shield adopts the compact Nano form factor, allowing it to mate seamlessly with the Arduino Nano ESP32 via standard pin headers.

Each LED on the matrix is individually addressable through a single digital control line, supporting 24-bit full-color rendering (8 bits per channel for Red, Green, and Blue) and cascading data transmission. By leveraging the powerful ESP32-S3 dual-core microcontroller (up to 240 MHz) embedded in the Arduino Nano ESP32, users can implement complex lighting algorithms, IoT-connected visual feedback systems, and real-time responsive light installations.

[Features]

• Tailored Form Factor: Custom-designed mechanical outline that perfectly matches the Arduino Nano ESP32 board, ensuring compact and reliable stacking.
• Programmable RGB LEDs: Programmable RGB LEDs; each pixel is independently addressable via a one-wire interface.
• High-Density Matrix Layout: Dense grid arrangement of RGB LEDs (visible as dual matrix arrays on the shield) for smooth graphics, icons, and animation rendering.
• Single-Pin Control: Requires only one GPIO pin (D11) to drive the entire LED matrix, freeing up other I/O for sensors and peripherals.
• Rich Color Depth: 256 brightness levels per color channel, supporting up to 16.7 million colors (24-bit RGB) per LED.
• Expandable Interface: Broken-out pin headers (D0-D10, D12, D13, 3V3, A0–A7, VBUS, GND, VIN, etc.) allow easy integration of additional modules, sensors, and external power.
• Plug-and-Play USB-C: Combined with the Nano ESP32’s USB-C connector for both power and programming, simplifying the development workflow.

• Compatibility: Arduino NANO ESP32: Supports Web UI/RMT demo; Arduino NANO R4: Supports basic Neopixel demo only

IMPORTANT NOTE

Please note: This RGB LED matrix generates significant heat as brightness increases. To prevent burns, do not set the brightness to maximum during initial debugging. When testing, avoid staring directly at the matrix for extended periods, as this may cause eye strain or discomfort; use a semi-transparent diffuser or cover to reduce glare if necessary. For prolonged operation, additional cooling or heat-dissipation equipment is strongly recommended to avoid high-temperature contact burns.

NOTE2: USB power is for low-brightness testing only
