This module combines a 0.96 inch OLED display with an EC11 rotary encoder, providing a compact solution for quickly creating a user interface.

Connecting the OLED via I2C allows for easy integration with Arduino and other development boards, with a reduced wire count. The OLED display provides high contrast and very good readability, and the rotary encoder provides precise control for menu navigation, selections and parameter adjustment.

The module also includes dedicated buttons for confirmation and return, making it suitable for control panels, simple HMI interfaces, and DIY projects where you need clear commands and immediate visual feedback.
