KY-040 Rotary Encoder Module (360° Incremental Encoder)

The KY-040 Rotary Encoder is a 360° incremental encoder used to detect rotation, direction, and step count. Each turn generates digital pulses that microcontrollers like Arduino, ESP32, and Raspberry Pi can easily read.
It is widely used in menu navigation, motor control, volume knobs, and robotics.

Key Features:

• 360° infinite rotation

• Detects direction (clockwise / counter-clockwise)

• Push-button switch included

• Generates stable digital pulses

• Easy to interface with Arduino

• Reliable and long-lasting

Applications:

• Volume / speed control

• Menu navigation in Arduino projects

• CNC and motor control

• Robotics & automation

• DIY electronics and user interfaces

Condition:
Brand New – High-Quality Module
