Rotary Encoder Module

This AX22-sized module integrates an ALPS Alpine incremental rotary encoder on a compact 22 × 22 mm PCB. The encoder outputs clean two-channel quadrature signals plus an optional push-switch, making it straightforward for any microcontroller to read direction, step count, and clicks without extra debouncing circuitry. It's perfect for tweaking parameters like brightness, volume, or menu selections. Use it standalone with any microcontroller, or snap it into the Genesis Modular system from Axiometa for plug-and-play integration. Works with Arduino IDE, MicroPython, or MicroBlocks.
