This module combines an OLEDIIC interface module and an EC11 rotary encoder module. The two are independent components placed on the same board as an integrated module, with additional and confirm buttons. The button interface is included and can be used according to actual usage. Integrated design provides a compact, clean appearance and is convenient for DIY projects. Key benefits Allinone display and input solution: OLEDIIC interface plus EC11 rotary encoder on a single board, with and confirm buttons, reducing wiring and panel space. Flexible button interface: button connections can be used as needed for different applications. Easy DIY integration: compact form factor and integrated layout simplify assembly and prototyping. Reliable input and display control: compatible with standard I2C OLED displays and EC11 rotary encoder inputs on a single module. Clear layout and accessibility: designed for straightforward installation in small enclosures or projects. Attributes Function: combines OLEDIIC interface module and EC11 rotary encoder module on one PCB with and confirm buttons. Compatibility: suitable for standard I2C OLED displays and EC11 rotary encoders; intended for common microcontroller platforms. Size: compact integrated board designed to minimize space in DIY projects. Material: PCBbased module suitable for typical hobbyist and development environments. Performance: designed to provide reliable I2C display control and knob input within an integrated package. Use scenarios Arduino or ESP32 projects: use the OLEDIIC interface to drive a display and navigate menus with the EC11 encoder, using and confirm buttons for quick selection. Small control panels for home automation or electronics projects: create a compact user interface with a display and knob input in a single module. Portable or handheld devices: integrate a display and rotary control in a spaceconstrained enclosure, reducing wiring and component count. Notes The OLEDIIC interface and EC11 rotary encoder are on the same board but function independently; the integrated module is designed to streamline assembly and usage in DIY projects.
