Digital Rotary Encoder Module

The Digital Rotary Encoder Module is an electromechanical device that converts the angular position or motion of a shaft into digital signals. It is commonly used in microcontroller projects for input devices like digital volume knobs, menu navigation dials, or position sensors. The encoder generates two square wave outputs (A and B) to determine direction and rotation, along with an optional switch button (C).

Key Features of Digital Rotary Encoder Module:

• Incremental Encoding: Outputs digital pulses for every incremental movement of the shaft.
• Dual Channel Output: Provides quadrature output (A and B channels) to detect direction.
• Push Button Function: Integrated push button on shaft for versatile user input.
• Long Service Life: High reliability with more than 30,000 rotational cycles.
• Easy Integration: Compatible with Arduino, Raspberry Pi, and other development boards.
