compatible with this OLED + EC11 Rotary Encoder module?\u003c\/h4\u003e\n\u003cp\u003eA: This module is compatible with a wide range of popular microcontrollers including Arduino (Uno, Nano, Mega), ESP8266, ESP32, STM32, and Raspberry Pi. Its IIC (I²C) interface ensures easy integration with minimal wiring — typically just VCC, GND, SDA, and SCL pins.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between the 0.96\" and 1.3\" versions?\u003c\/h4\u003e\n\u003cp\u003eA: Both versions share the same 128×64 resolution and EC11 rotary encoder integration. The primary difference is physical screen size — the 1.3\" version has a larger display area, making text and graphics slightly bigger and easier to read, while the 0.96\" version is more compact and ideal for space-constrained builds.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the EC11 rotary encoder include a push-button function?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The EC11 rotary encoder on this module includes a built-in push-button (click) function, allowing you to use it for both rotary navigation and selection inputs — perfect for menu-driven interfaces and parameter control in your projects.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I display custom graphics or text on this OLED module?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The 128×64 OLED display is fully programmable and works with popular libraries such as Adafruit SSD1306 and U8g2, enabling you to render custom text, icons, graphics, and animations tailored to your specific application.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
