5pcs 360 Degree Rotary Encoder Module KY-040 Brick Sensor Development Board with Push Button for Arduino

Description

5pcs 360° Rotary Encoder Module KY-040 – Precision Input for Arduino Projects

Upgrade your DIY electronics with the KY-040 360° Rotary Encoder development board, now available in a convenient pack of five. Designed for seamless integration with Arduino, Raspberry Pi, ESP32, and other micro‑controller platforms, this compact sensor delivers smooth, high‑resolution rotation detection and a reliable push‑button click.

Key Highlights

• Full 360° rotation with 20 steps per detent (120 pulses per revolution) for precise position tracking.
• Integrated push‑button for instant user input – perfect for menu navigation and control panels.
• Compact “brick” form factor (12 mm × 12 mm) fits easily on breadboards and PCB prototypes.
• Standard 5‑pin header (VCC, GND, SW, DT, CLK) compatible with Arduino UNO, Nano, Mega, and most development boards.
• Low power consumption (3.3 V – 5 V) and robust mechanical construction for long‑term reliability.
• Package includes 5 units – ideal for multi‑project labs, teaching kits, or bulk inventory.

Why Choose the KY-040 Rotary Encoder?

The KY-040 offers a tactile, high‑resolution interface that translates rotary motion into clean digital signals. Whether you’re building a volume knob, a jog wheel, a CNC controller, or an interactive art installation, this encoder provides the accuracy and durability you need without complex wiring.

Easy Integration & Development

Connect the five pins directly to your micro‑controller and start coding in minutes. Sample Arduino sketches are included, demonstrating:
