1W RGB LED module — high-power full-colour LED, common anode, Arduino compatible
This 1W RGB LED module integrates a high-power 1 watt RGB LED onto a compact breakout board, making it easy to add vibrant, full-colour lighting to Arduino, ESP32, Raspberry Pi, and other microcontroller projects. The module combines red, green, and blue LED dies in a single package, allowing any colour to be produced through PWM mixing of the three channels.
With a common anode configuration and onboard current-limiting resistors (on some variants), it is straightforward to drive directly from a microcontroller PWM output or via a dedicated LED driver. Ideal for mood lighting, interactive displays, RGB indicators, and creative DIY lighting projects.
Key Specifications:
- LED power: 1W (total, RGB combined)
- LED type: high-power RGB LED (red + green + blue dies)
- Configuration: common anode
- Forward voltage: Red ~2.0–2.2V, Green ~3.0–3.4V, Blue ~3.0–3.4V (typ.)
- Forward current: ~350mA per channel (at full 1W drive)
- Colour mixing: full spectrum via PWM control of R, G, B channels independently
- Interface: 4-pin (R, G, B, common anode/VCC)
Key Features:
- High-power 1W RGB LED — significantly brighter than standard 5mm through-hole RGB LEDs
- Full-colour mixing — produce any colour by independently PWM-controlling R, G, and B channels
- Compact module form factor — easy to integrate into breadboard and PCB designs
- Arduino and ESP32 compatible — drive with analogWrite() PWM or via MOSFET/transistor driver for full current
- Common anode design — connect VCC to anode, pull each colour channel low to activate
Applications:
- Arduino and ESP32 RGB lighting projects
- Mood lighting and ambient light controllers
- Interactive colour-changing displays and indicators
- RGB status indicators for enclosures and panels
- Photography and studio lighting effects
- DIY smart home lighting nodes
Note: At full 1W drive (350mA per channel), a heatsink or adequate thermal management is recommended. For Arduino direct drive, use a MOSFET (e.g. IRLZ44N) or transistor (e.g. 2N2222) per channel to handle the current — Arduino GPIO pins are limited to ~40mA. Use PWM pins for smooth colour mixing.
