🎛️ 1.3" OLED Display with EC11 Rotary Encoder (I2C)

💡 Integrated Display + User Input

The 1.3" OLED Display with EC11 Rotary Encoder provides both display output and user input in one module. The high-resolution 128x64 OLED communicates via I2C, while the EC11 encoder includes push-button support — ideal for menu navigation or control panels in embedded projects.

🛡️ Features

• 📺 1.3" 128x64 OLED display, crisp and bright
• 🔄 EC11 rotary encoder with push-button
• 🔌 I2C interface for display (only 2 wires)
• 🧠 SSD1306 compatible OLED controller
• 📏 Compact footprint, breadboard-friendly
• 🔋 Low power consumption

🛠️ Applications

• 🎮 Menu-based UI for Arduino or ESP32 projects
• ⚙️ Device control panels
• ⏲️ Timers or digital counters
• 📟 Parameter tuning interface
• 🧪 Embedded test systems
• 🔧 DIY electronics & robotics

⚠️ Notes

• 🧰 Libraries needed: Adafruit_SSD1306 or U8g2 for display
• ⚠️ Use pull-up resistors on encoder if needed
• 📐 I2C OLED address: usually 0x3C
• ⛔ Encoder pins must be wired to GPIOs separately (not via I2C)

✨ Key Advantages

• 🖥️ Combined input + output module
• 📉 Reduces wiring with I2C
• 🧱 Well-supported by open-source Arduino libraries
• 🔄 Interactive and dynamic UI building
• 🔌 Easy to integrate in space-limited designs
