KY-016 3 Color LED Module

KY-016 DIP 3 Color LED Module is a versatile RGB LED module designed for Arduino and other microcontroller platforms. It combines red, green, and blue LEDs into one DIP-style 5mm LED to produce a wide range of colors by varying the PWM input signals. The module is ideal for DIY electronics projects, prototyping, and learning color mixing techniques in embedded systems.

Key Features:

• 3-in-1 RGB LED: Integrates red, green, and blue LEDs in a single DIP LED package.
• PWM Control: Allows color blending through pulse-width modulation.
• Common Cathode: All three LEDs share a common ground connection.
• Standard Interface: 4-pin header compatible with jumper wires and breadboards.
• Educational Use: Ideal for learning basic electronics and RGB color theory.

Technical Specifications:

• Operating Voltage: 5V DC
• LED Type: DIP 5mm RGB (Common Cathode)
• Current (Typical): ~20mA per color channel
• Pinout: R, G, B, and GND
• Wavelength (typical): Red: 620-630nm, Green: 515-525nm, Blue: 465-475nm

Mechanical Specifications:

• Module Dimensions: Approx. 19mm x 15mm
• LED Size: 5mm round DIP LED
• Header Type: 4-pin male header
