Great for status indicators
Bought five of these for my robot project to indicate different states. They are compact and consume low power. Fast shipping too.

Easy to connect
I am new to electronics and this was very forgiving. Connected it to 5V and ground and started blinking colors immediately. Highly recommend.

Good quality module
Works as described. The only minor issue is that the pin headers were slightly tight on my breadboard, but nothing a little adjustment couldn't fix.

Perfect for learning color mixing
I used this module for a school project with Arduino. The colors are bright and the code was straightforward to write. Great value for beginners.

Bright and vivid colors
The SMD LED is surprisingly bright. Works perfectly with my micro:bit setup. Pinout is standard which makes wiring easy.
Q: What is the maximum current draw per color channel?
A: Each color channel draws approximately 20mA at full brightness. Ensure your microcontroller pin can handle this load.
Q: What is the exact pinout configuration?
A: The pins are typically labeled GND, VCC, R, G, and B. Please check the silkscreen on the PCB for verification.
Q: Does this module support 3.3V logic levels?
A: Yes, this module is designed to work with both 3.3V and 5V logic systems safely.
Q: Do I need a specific library to use this with Arduino?
A: No specific library is required. You can control the colors using standard digitalWrite and analogWrite functions.
Q: Can I use PWM to fade the colors?
A: Yes, connecting the RGB pins to PWM-enabled pins on your microcontroller will allow you to fade and mix colors smoothly.
