ALLNET 4duino Rotary Encoder (ALL-4duino-Encoder)

The ALLNET 4duino Rotary Encoder (ALL-4duino-Encoder) is a high-quality incremental rotary encoder designed for Arduino, ESP32, Raspberry Pi, and other microcontroller projects. It provides precise quadrature output with a push-button switch, making it ideal for menu navigation, volume control, and position sensing applications.

Advantages

This encoder offers reliable 20 pulses per revolution (PPR) with a 360° continuous rotation angle. The integrated push-button adds extra functionality, and the knurled shaft ensures easy knob attachment. Its compact PCB mount design and 2.54mm pin header interface simplify integration into your projects.
