Your Arduino project is powerful... but does it look alive?

Product Name:  RGB LED Matrix Expansion Board for Arduino Nano ESP32 
Product SKU: EP-0263

Meet the RGB LED Matrix Shield — the fastest way to give your Nano board a visual voice.

🎯 The Problem It Solves:
Arduino projects often work perfectly but give zero visual feedback. This shield changes that instantly.

🔧 What You Get:
• 104 individually addressable RGB LEDs in a compact Nano form factor
• Zero wiring mess — just align the headers and press it in
• Single data pin (D11) control — all other I/O pins stay free for sensors & modules
• USB-C power & programming through your Nano board
• Ready-to-run demos: Rainbow, Breathe, Chase, Twinkle, Heartbeat, Smiley Face

📱 Web Control (Nano ESP32):
Connect to the same 2.4 GHz Wi-Fi network and control mode, brightness, and speed from any browser — no re-uploading code.

🌍 Real-World Uses:
• Desk mood light & ambient display
• IoT server status & sensor alert indicator
• STEM classroom teaching tool
• Pixel art badge, mini sign, or interactive prop

⚠️ Quick Safety Note:
Start with low brightness. At high brightness, RGB LEDs draw more power and generate heat. For extended high-brightness use, add a proper 5V external power supply with correct GND connection.

Stack it. Plug it. See it.
