KY-009 SMD RGB LED Module features a 5050 PWM RGB SMD LED with built-in current-limiting resistors for safe, full-color light mixing. Compatible with Arduino, Raspberry Pi, and other MCUs. Compact 19×14×5 mm form factor.

 

The KY-009 SMD RGB LED Module (MPN: KY-009) is a compact 5050 PWM RGB SMD LED breakout board designed for makers, students, and engineers who need full-color light output with minimal wiring. By combining three primary colors — Red, Green, and Blue — via PWM signals, the module can reproduce a virtually unlimited palette of colors, making it ideal for status indicators, ambient lighting projects, and visual feedback systems.

Κύρια Χαρακτηριστικά / Key Features

  • 5050 RGB SMD LED: High-brightness tri-color LED in a single package → full-color mixing in a tiny footprint
  • Built-in current-limiting resistors: Onboard resistors protect the LED from over-current → no external resistors needed, safer wiring
  • PWM color mixing: Each color channel is independently PWM-controllable → smooth gradients and millions of color combinations
  • Universal MCU interface: Works with a wide range of microcontrollers and single-board computers → easy integration into existing projects
  • Ultra-compact & lightweight: 19×14×5 mm, 2 g → fits in space-constrained enclosures

Pinout & Wiring

PINSymbolDescription
1RRed channel — connect to PWM-capable digital output
2GGreen channel — connect to PWM-capable digital output
3BBlue channel — connect to PWM-capable digital output
4GNDCommon ground (negative power rail)

Wiring note: Connect GND to the board ground. Drive each color channel (R, G, B) from a PWM-capable pin on your microcontroller. Onboard resistors are already included — do not add additional series resistors on the signal lines.

Compatibility

  • Arduino UNO / Nano / Mega: Directly compatible — use the 5 V PWM pins (e.g., D3, D5, D6, D9, D10, D11) for each color channel.
  • Raspberry Pi / ESP32 / ESP8266: Compatible via PWM-capable GPIO pins. Use logic-level considerations appropriate to your board.
  • General MCU: Any microcontroller with PWM output can drive this module.

Typical Applications

  • Color-coded status indicators in DIY electronics enclosures
  • Ambient mood lighting controlled by Arduino or ESP32
  • Visual feedback in robotics and automation projects
  • Learning PWM and color mixing concepts in educational settings
  • Decorative lighting effects for cosplay, props, and displays

Frequently Asked Questions

Q: Do I need external resistors to use the KY-009 with Arduino?
A: No. The KY-009 includes onboard current-limiting resistors on all three color channels, so you can connect it directly to your microcontroller's PWM pins without adding external resistors.

Q: Can I use this module with an ESP32 or Raspberry Pi?
A: Yes. The module is compatible with any MCU that provides PWM-capable GPIO pins, including ESP32, ESP8266, and Raspberry Pi.
