## Description

If you have damaged your 4x4x4 RGB LED Cube during assembly or need to replace some LEDs then order this pack to repair your cube. We also offer the [horizontal](https://core-electronics.com.au/Horizontal%20Plane%20PCB%20pack%20for%20Freetronics%204x4x4%20RGB%20LED%20Cube) and vertical plane PCBs in separate packs.

Huge 8mm RGB (Red Green Blue) LEDs in a 4-pin package with a common cathode (negative) connection. Great for building colourful displays or status indicators that change colour! Comes in a handy 8-pack.

The "cathode" is the negative side of the LED, so having a common cathode means you can connect the cathode pin to 0V (GND) and then switch on the individual RGB elements by connecting their pins to +V using current limiting resistors. Using PWM pins on your Arduino you can then blend the red, green and blue colours together to create any colour you like.

*Note: We also have "common anode" LEDs available.*

The pack contains the following items:

- 8 x RGB LEDs (note: common **cathode**)
