Boardoza Rotary Encoder EC1101S Breakout Board
The Boardoza Rotary Encoder EC1101S Breakout Board is a multifunctional input and visual feedback solution that combines a mechanical rotary encoder, an integrated push button, and addressable RGB LEDs (ARGB) on a single compact PCB. The board converts rotational movement into digital signals while enabling dynamic visual effects through programmable LEDs. With 14 cascaded ARGB LEDs arranged around the encoder, the board can visually represent rotation, direction, speed, and system status. Encoder movements can be processed by a microcontroller such as an Arduino or ESP32 to control LED color, brightness, and animation patterns. This makes the board ideal for interactive user interfaces, control panels, visual feedback systems, and creative electronics projects.
Key Features
- Rotary Encoder with Push Button: Mechanical rotary encoder with integrated momentary push button for menu navigation and user input.
- Integrated Addressable RGB LEDs: Features 14 cascaded ARGB LEDs for dynamic visual feedback and animation effects.
- Quadrature Output Signals: Provides A and B channel outputs for accurate direction and rotation detection.
- Visual Motion Representation: Encoder rotation can be visually expressed through programmable LED color, pattern, and brightness changes.
- Wide Logic Compatibility: Fully compatible with both 3.3 V and 5 V microcontroller systems.
- Expandable LED Chain: ARGB data and clock input/output pins allow cascading with additional LED boards.
- 20 Pulses per Revolution: Provides 20 pulses per 360° rotation (per phase) for precise rotational detection.
